On August 31, the Comprehensive Department of the National Energy Board issued an announcement on the public solicitation of opinions on the "Administrative Regulations on Grid-connected Entity and Operation (Draft for Comments)" and "Administrative Measures for Auxiliary Services of the Power System (Draft for Comments)". The "Regulations" and "Measures" will be implemented from the date of promulgation, with a validity period of 5 years.
The "Administrative Regulations on Grid-Connected Operation of Grid-connected Entities" apply to the thermal power, hydropower, nuclear power, wind power, photovoltaic power generation, pumped storage, new energy storage and other grid-connected entities that are directly dispatched by provincial-level and above power dispatching agencies, and can respond to provincial-level and adjustable loads ordered by the above power dispatching agencies (including those aggregated through aggregators, virtual power plants, etc.), self-supplied power plants, and conditionally participating grid-connected entities that can be indirectly dispatched by municipal-level and below power dispatching agencies (Collectively referred to as grid-connected entities).
The “Regulations” point out that the grid-connected entities on the power generation side should work with grid companies in accordance with the principles of equality and mutual benefit, consensus and ensuring the safe operation of the power system, with reference to the "Grid-connected Dispatching Agreement (Model Text)" and "Power Purchase and Sale Contract (Model Text) 》Sign the grid-connected dispatch agreement and the electricity purchase and sale contract in time, and must not connect to the grid without agreement. Other grid-connected entities shall sign relevant agreements and contracts in accordance with relevant regulations.
When a grid accident or network security incident occurs, the grid-connected entities on the power generation side shall not be connected to the grid until the cause has been identified, and other grid-connected entities shall not participate in grid regulation before the cause has been identified.
The "Administrative Measures for Power System Auxiliary Services" apply to the provision, invocation, assessment, compensation, settlement and supervision and management of power auxiliary services within the dispatching jurisdiction of power dispatch agencies at the provincial level and above. The main power auxiliary service providers include thermal power, hydropower, and nuclear power. Grid-connected entities (collectively referred to as “grid-connected entities,” such as wind power, photovoltaic power generation, pumped storage, new energy storage, etc., as well as user-adjustable loads that can respond to dispatch instructions (including adjustable loads aggregated through aggregators, virtual power plants, etc.) "). The grid-connected resources and qualified self-provided power plants dispatched by electric power dispatching agencies at the municipal level and below may be included in the local electric power auxiliary service management implementation rules or market transaction rules.
The "Measures" pointed out that when the agencies dispatched by the National Energy Board formulate the implementation rules for the management of auxiliary power services, in principle, they mainly stipulate the relevant mechanisms for the types of auxiliary power services obtained through voluntary provision and fixed compensation; in formulating the auxiliary power service market When trading rules, it mainly stipulates the relevant mechanisms of primary frequency modulation, secondary frequency modulation, peak shaving, standby, moment of inertia, climbing and other electric auxiliary service varieties obtained through marketization.
Power users participate in the ancillary service are involving in a sharing mechanism. According to the principle of “ provides, benefits, and bears” principle, gradually establish an ancillary service sharing and sharing mechanism in which power users participate, and differentiate the sharing of different types of power users according to local conditions. Power users can participate in power auxiliary services through independent participation and entrusted-agent participation.
Cross-province and cross-regional power transmission supporting power supply units, "point-to-grid" units, "point-to-point" units, and "network-to-grid" units shall be included in the management of auxiliary power services in accordance with these measures, and be connected to the receiving end or the transmitting end according to actual operation conditions. The power grid participates in auxiliary power services, in principle, it does not repeatedly participate in the transmission and management of auxiliary power services at both ends.
The new version of the "Two Rules" expands the new main body of grid-connected operation management and auxiliary services, adds new types of power auxiliary services, improves the new mechanism for sharing and sharing auxiliary services, reduces the increasing auxiliary service costs of power system operation, and improves more flexibility. The market-based price competition mechanism further reduces system operating costs. The new version of the document lays a new foundation for the construction of my country's auxiliary service market, improves the deficiencies of the original mechanism under the new situation, conforms to the new changes and new needs of my country's energy structure transformation, and matches the reform and construction of my country's power market, which will be effective stimulate the vitality of the market and promote the continuous emergence of new business models.
The new version of the "Two Rules" covers all key elements such as new grid-connected entities, new types of auxiliary services, technology access, participation mechanisms, demand determination, invocation mechanisms, assessment mechanisms, compensation mechanisms, and apportionment mechanisms, indicating that the country will give full play to The determination of the market mechanism, only through the formation of transaction prices through the market mechanism, reducing the cost of system auxiliary services, and optimizing system operation efficiency, can the decisive role of the market in resource allocation be better played, and new energy storage, virtual power plants, etc. can be better played The value and role of new technologies.
After the release of the new "Two Rules", it will be able to better guide the construction and implementation of the local auxiliary service market. In this process, we believe that energy storage as a new technology and new entity will fully participate in the construction and competition of the market Play its role and value. In this process, the China Energy Storage Alliance is preparing to establish an auxiliary service committee, which will provide think tank support for all parties in the industry, and jointly promote energy storage to participate in related work in the auxiliary service market.
