In accordance with the relevant requirements of the National Energy Administration, under the guidance and guidance of the Market Supervision Department of the National Energy Administration, the Northeast Energy Regulatory Authority started the system based on the experience of the operation of the power-assisted service market in the early stage, combined with the new situation and new problems arising from the operation of the Northeast Power. New ancillary services market rules development work. After more than half a year of careful preparation, the “Northeast Electric Power Auxiliary Service Market Operation Rules (Provisional)†was issued recently, and the simulation operation of the new rules was launched, marking the overall upgrading of the Northeast Electric Power Auxiliary Service market rules.
I. Implementing the new requirements of state auxiliary services and grasping the new situation of Northeast Electric Power
In accordance with the spirit of the No. 9 Document of the Central Electric Power Reform on the establishment of a new mechanism for sharing auxiliary services, the National Energy Administration issued the Work Plan on Improving the Compensation for Electric Power Auxiliary Services (Market) Mechanism at the end of 2017 (Guo Neng Fa Supervision [2017] No. 67) It is required to increase the amount of backup compensation and encourage power generation enterprises to provide auxiliary services through bidding. In early 2018, the National Development and Reform Commission and the National Energy Administration issued the "Guiding Opinions on Improving the Regulating Ability of the Power System" (Development and Reform Energy [2018] No. 364) It is required to speed up the power-side adjustment capability, share peak-shaving and backup resources in the regional power grid, and improve the power-assisted service market mechanism. These documents all put forward higher requirements for reforming the power auxiliary service mechanism. In this regard, the Northeast Energy Regulatory Authority firmly implements the national requirements and thoroughly explores the marketization path of auxiliary services.
In the past two years, the problem of peak trough peaking in the Northeast Power Grid has been significantly alleviated, but some new situations and new problems have emerged. It is reflected in the fact that although the thermal power-on capacity is large, the peak capacity of the unit is seriously reduced due to factors such as heat supply and coal quality. The reserve capacity of the grid is insufficient during the peak period, and the power consumption of the grid is faced with an orderly power consumption. The safe and stable operation of the grid faces new challenges. In response to new situations and new problems in the operation of Northeast Power, the Northeast Energy Regulatory Authority considered it necessary to comprehensively upgrade the “Northeast Power Assisted Services Market Operation Rules (Trial)â€.
Second, careful deployment, condensing wisdom, and formulating new market rules
The Party Group of the Northeast Energy Regulatory Bureau attaches great importance to the revision of the operational rules of the auxiliary service market. As a key work in 2018, it has carried out research and deployment many times and has formulated a careful work plan. According to the work plan, the revision of the power-assisted service market rules was launched in May 2018. In June, an in-depth investigation was conducted. Subsequently, all market members were consulted on the revision work. In August, the northeast power auxiliary service market upgrade direction and rules were determined. Revise the focus; in September, more than 20 experts will be drafted and revised to form the “Northeast Electric Power Auxiliary Service Market Operation Rules (Draft for Comment)â€; in October, all members of the market will be consulted and revised according to feedback; 12 In the middle of the month, the Expert Evaluation and Demonstration Meeting of the "Northeast Electric Power Auxiliary Service Market Operation Rules" was held. The experts unanimously passed and highly praised it. At the end of December, the "Northeast Electric Power Auxiliary Service Market Operation Rules (Provisional)" was officially issued (hereinafter referred to as "new rules" "), at the same time deploying from January 1, 2019, starting from 0:00, start the market simulation operation according to the new rules.
It can be said that the revision process of the rules is also a process of in-depth investigation and research, extensively promoting democracy, and condensing the wisdom of all market members.
Third, the innovation mechanism to achieve a comprehensive upgrade of the Northeast Electric Power Auxiliary Service Rules
The comprehensive upgrade of the Northeast Electric Power Auxiliary Service Rules is reflected in two aspects:
The first is to add a rotating reserve trading variety to achieve full coverage of the auxiliary service market "depressing the valley and peaks." Rotating standby refers to the service provided by the genset during the peak period by reserving the rotating reserve capacity in order to ensure reliable power supply. In order to motivate and guide the thermal power plant to actively upgrade the peak capacity, the new rules have designed a pre-bidding mechanism for the peak rotation reserve market. The thermal power plant recently reported the maximum power generation capacity and standby selling price, which is a statistical cycle every fifteen minutes. The Northeast Rotary Reserve Transaction uses the peak power capability of the power plant as the subject of trading. There are three innovations in the mechanism: First, the implementation of the unified platform trading in the Northeast, completely breaking the inter-provincial barriers to auxiliary services; The crew can obtain the full auxiliary service income and put forward the complete flexibility standard for the thermal power unit capacity. Thirdly, the unit power generation capability assessment adopts the system random automatic sampling method, which reduces the manual operation amount of the dispatching organization and minimizes human interference. .
Secondly, the original deep peak shaving compensation mechanism was improved. First, the real-time deep peaking cost of the non-heating period will be halved. At the same time, the wind power and nuclear power will be shared according to twice the heating period, so as to accurately reflect the scarcity of peaking in the northeast heating period and benefit new energy. More equal to the cost of the apportionment. Second, considering the rapid development of photovoltaics in the Northeast, the peaking of the power system has been significantly affected, so the PV is formally included in the power auxiliary service market. The third is to set an upper limit on the sum of provincial and inter-provincial peak-sharing expenses undertaken by market entities, and to play a “bottom line†protection role for market entities that have no adjustment ability or weak adjustment ability. The fourth is to refine and optimize the calling principle and execution flow of the deep peaking auxiliary service.
Fourth, the new mechanism of simulation operation test, improve the new rules
In accordance with the notification requirements for the issuance of new rules, the Northeast Electric Power Auxiliary Service Market has been carrying out simulation operations in accordance with the new rules since January 1, 2019. During the simulation operation, the system platform will carry out data statistics, simulation assessment, and information release. The power generation enterprise will carry out simulation declaration and simulation settlement, and the actual operation rules and settlement of the market will still implement the original operation rules. The market simulation operation will play the role of testing rules, accumulating experience, and training market players. The new rules will be adapted to the appropriate content based on the simulation results and will be transferred to the formal implementation phase as appropriate.
After the new rules are officially implemented, it is expected to continue to alleviate the peaking of the northeast power grid, and at the same time alleviate the problem of thermal power generation in the peak period to ensure the stable supply of power in Northeast China, improve the operational flexibility of the Northeast power system, and further promote the Northeast energy supply revolution and system. revolution.
