Analysis and suggestions on the current situation of Zhejiang power market construction

by the end of 2016, the installed power capacity of the province was 83310 MW, an increase of 2.1% year-on-year. Among them, the total installed capacity of power generation above 6000 kW was 79270 MW, an increase of 2680 MW year-on-year. The installed capacity of East China and the province is 69130 MW, an increase of 2540 MW year-on-year. The total power generation of the province is 319.8 billion kwh, of which 600 high-temperature 3D printing equipment has the following characteristics: the generating capacity of units above 0 kW is 310.9 billion kwh, an increase of 7.1% year-on-year. The generating capacity of thermal power units was 237.4 billion kwh, with a year-on-year increase of 7.0%, and the average utilization hours of installed capacity was 3919 hours, with a year-on-year decrease of 31 hours. The maximum load of provincial unified dispatching was 65480 MW, an increase of 11.9% year-on-year. The maximum daily power consumption of unified regulation is 1.308 billion kwh. The maximum peak valley difference of unified regulation throughout the year is 22570 MW, the average peak valley difference is 15730 MW, and the average power load rate is 82.7%

at the end of 2016, the installed capacity of heating units in the province was 13240 MW, accounting for about 15.9% of the total installed capacity of electricity in the province, an increase of 4.3 percentage points year-on-year. Among them, there are 124 local cogeneration enterprises with an installed capacity of 4040 MW, accounting for 30.5% of the heating units in the province, a year-on-year decrease of 13.3 percentage points. A total of 41 urban domestic waste incineration power generation enterprises and 7 sludge incineration power generation enterprises have been built in the province. The cumulative installed capacity was 641 MW, with a year-on-year increase of 5.6%. The annual power generation was 4.99 billion kwh, with a year-on-year increase of 43.8%. The domestic waste incineration capacity is 317.85 million tons/day, and the sludge incineration capacity is 2.89 million tons/year

by the end of 2016, the total length of 110kV and above transmission lines in the province was 50641 kilometers, and the transformation capacity was 362.02 million KVA

in 2016, the electricity consumption of the whole society was 387.3 billion kwh, an increase of 9% year-on-year. It accounts for 53.6% of the province's final energy consumption. The net electricity transferred from other provinces was 67.6 billion kwh, an increase of 24.5% year-on-year, accounting for 17.5% of the total electricity consumption of the province

in 2016, the province's per capita electricity consumption was 6929 kwh, an increase of 8% year-on-year. The per capita electricity consumption for work and life was 924 kwh, an increase of 15.3% year on year. The electricity consumption of the primary industry, the secondary industry and the tertiary industry accounted for 0.7%, 72.7% and 13.3% respectively; Domestic electricity consumption accounts for 13.3%. There are 27.11 million power users in the province, including 2657923 industrial and commercial users. The actual average household electricity price is 753 yuan/kWh

II. Progress of Zhejiang power market construction

in 2016, the pilot scheme of Zhejiang Province's electricity sales side reform and the pilot scheme of transmission and distribution price reform were submitted to the national development and Reform Commission and the National Energy Administration for approval and approval. An electricity trading agency was established, the transmission and distribution electricity price was calculated and submitted to the national development and Reform Commission for approval. Six incremental power distribution and three micro power projects were included in the national pilot

actively expand the scale and scope of direct electricity trading. In 2016, two batches of direct electricity trading were carried out, with 74.7 billion kwh of direct electricity trading, reducing the power consumption cost of enterprises by about 4.176 billion yuan. This year, direct electricity trading will continue. It is estimated that the direct trading electricity will be about 93billion kwh, and the electricity price will be reduced by about 0.03 yuan/kWh. From January to September, 72.759 billion kwh of direct trading electricity has been accumulated, with an average reduction of electricity price of 3.06 cents/kWh and 2.226 billion yuan. The comprehensive pilot plan for the reform of Zhejiang electric power system (hereinafter referred to as the plan) was issued

III. characteristics of the plan

(I) the plan clearly puts forward that the goal of Zhejiang power market is to "establish a provincial power market system with the spot market as the main body and the power financial market as the supplement." Especially in the initial stage, the power market aims to build a spot market, which will have a profound impact on the construction of Zhejiang and even the national power market

(II) the plan defines the medium-term market, explores the renewable energy market participation mechanism, and promotes the trading of energy green certificates. The participation of renewable energy in the market and green certificate trading will make the construction of Zhejiang power market more distinctive, which can not only ensure the full purchase of renewable energy power generation, but also promote the sustainable and benign development of renewable energy

(III) market construction is divided into three stages, reflecting the idea of active, steady and step-by-step implementation. The plan clearly puts forward that the construction of Zhejiang power market should follow the principle of scale from large to small, trading varieties should be gradually increased, trading mechanism should be gradually improved, and market mode should be gradually optimized, and it should be divided into three stages: initial market, medium-term market and target market

(IV) do not rush for success in the timing of market construction to ensure orderly progress. The time span of market construction from planning and design to the realization of the target market takes more than 7 years. On the basis of completing the verification of transmission and distribution electricity price, the establishment of relatively independent trading institutions, the formulation of market rules, and the completion of technical support system, the initial power market trial operation will be realized in the first half of 2019. By 2020, a relatively complete power market system will be basically formed, and then transition to the medium-term power market. By 2022, the target power market in Zhejiang will be established

(V) although the potential scope of the market is considerable, the scheme pays attention to drawing on the construction and operation experience of domestic and foreign power markets. The plan specifies that according to the initial market construction objectives, competitive negotiation and other ways, international and domestic consulting teams with rich experience in power market design and operation are introduced to assist in market design and construction

IV successfully introduced a consulting team with experience in the construction and operation of the power market

in September, the international competitive negotiation of the consulting project of the rules of Zhejiang power spot trading market was implemented. Through two rounds of competition and many negotiations, the consortium composed of PJM and China power scientific research was finally spent. At present, the relevant work after winning the bid is being carried out as planned

PJM is a non joint stock limited company established on March 31, 1997 with the approval of the Federal Energy Regulatory Commission (FERC), which is actually an independent system operator (ISO). PJM is currently responsible for the operation and management of power systems in 13 states and the District of Columbia. As a regional ISO, PJM is responsible for centralized dispatching of the largest and most complex power control area in the United States. The service population of PJM control area is about 65million. The total installed capacity is 68564 MW. Among them, 19437 MW is coal power, 15898 MW is gas power, 29826 MW is nuclear power, 337 MW is hydropower, 270 MW is oil power, 1762 MW is wind power, 433 MW is composite fuel power, and 481 MW is other fuel power. Among them, 2580 MW of renewable energy (86 MW of wood, 337 MW of water power, 395 MW of urban waste, 1762 MW of wind energy). The transmission line is about 13000 kilometers long. PJM power market has been operating for nearly 20 years. It is one of the first regional power markets in the United States and even the world to carry out power market reform. From the current real-time operation data, the market operating load is about 86000 MW, which is larger than the local power generation capacity, indicating that there is also cross regional power trading. No matter from the power installation suggestions in the market: when we do not use the plastic tensile testing machine, the structure and electrical system characteristics are similar to Zhejiang electric power

founded in 1951, China Electric Power Research Institute is a scientific research institution directly under the State Power Corporation of China. It is a professional research institution of electric power that enjoys a high reputation in China's power industry. It has strong technical research and development capabilities and rich engineering practice experience, has a high-level scientific research team, and has gathered a group of experts and scholars with deep theoretical foundation and rich practical experience. Engaged in the research of ultra/ultra high voltage AC/DC transmission and transformation technology, power planning analysis and safety control technology, transmission and transformation engineering design and construction technology, power distribution technology, new energy, new materials, power electronics, information and communication, energy efficiency evaluation and energy conservation, covering all aspects of power science and related fields. The UHV and large power test and research system with the most complete functions, the strongest test capability and the highest technical level in the world has been established. I have accumulated some experience in the construction of power market and the design of technical support system. Have a comprehensive understanding of the operation status of Zhejiang power system

the consulting consortium formed by PJM and China Electric Power Research Institute is a strong joint team, which has advantages in terms of talent composition, theory and practical experience. PJM brings experience in the construction and operation of power spot market. China Electric Power Research Institute has mastered domestic power regulations and policies, power market conditions and the operation characteristics of Zhejiang power system, and can realize complementary advantages, Ensure the orderly progress of the consulting project and achieve the consulting objectives on schedule

five difficulties and suggestions that may be encountered in the process of market construction

(I) the operation of Zhejiang power structure system is relatively complex, which is not conducive to the construction of spot trading market. First, the proportion of external electricity in Zhejiang is relatively large, accounting for about 1/3 in peak seasons. These electricity are basically planned or ordered by the government. Second, the security concerns of UHV AC/DC hybrid power operation have certain disadvantages to spot market transactions. Third, the installed capacity of nuclear power accounts for a large proportion. At present, the installed capacity of nuclear power has reached 6570 megawatts, which will reach 9070 megawatts when the initial power market target is achieved, accounting for about 10% of the installed capacity of the province. The actual operating power in the market will account for more than 10%, making it difficult to participate in spot transactions

(II) the design of market rules involves multiple objectives. The optimization of multiple objectives is a compromise result, but it is not an optimized spot market. The appropriate weight of spot should be reflected in the design of market rules

(III) the forces and directions of various market players are different, which may affect the construction process of the power market. Due to the different relevance of interests, the direction of their forces is not the same, which plays a promoting role, but also has an impeding role that cannot be ignored. There is a wide gap in strength between market players, and few can be compared with many, which is not a fair competition with equal strength. The government needs to have sufficient capacity and implement strong guidance to ensure that the market construction and operation have sufficient positive energy and the force opposite to the goal of the plan

(IV) the national energy administration should create conditions for its agencies to strengthen the supervision of the design, construction and operation of the provincial power market, especially to play its due role in the design and operation supervision of market rules

Zhejiang is a province with a relatively developed market economy. The society has an open consciousness and a generally strong market concept. At zero o'clock in January 2000, the unilateral contract power market was first launched in the country, and the plant separation reform was terminated in early 2003. Zhejiang power system has a sense of reform and innovation, and has accumulated experience in the construction and operation of the power market. There are a group of management and technical talents who are enthusiastic about the reform of the power market, and they have not forgotten the original intention of the power reform. Zhejiang is also one of the pilot provinces of the national power spot market, and the provincial government and relevant departments attach great importance to and make great efforts to promote it. The construction of Zhejiang power spot market will continue to be a national precedent
