Specifically, emergency demand response users participate in demand response capacity trading, where cleared response capacity in the trading receives reserve capacity revenue monthly.
During the trial run, the highest upper limit of clearing price is set, and the urgent peak clipping and valley filling demand response transaction is temporarily executed according to 0.5 yuan/kilowatt.
The information release is that an operation organization releases related transaction information such as capacity demand, maximum price, transaction time and the like; the transaction declaration is a demand response user declaration price curve, and the declaration transaction information comprises response capacity, capacity quotation, notification advance time, response duration, recovery commissioning time and the like; the trading clearing is achieved by adopting a unilateral bidding mode and sequentially clearing from low to high according to the principles of price priority, time priority and capacity priority and according to the price declared by the user until the winning user meets the emergency peak clipping demand response requirement value to form a capacity trading clearing price, and the clearing result is revealed to the participating users to form an emergency peak demand response resource bidding library. The response execution means that when the spare capacity of the power grid is insufficient or the local load is overloaded or a power supply gap is caused by other uncertain factors, an operation mechanism provides a demand response starting request, the execution range is determined according to the peak clipping capacity actually required after the request is confirmed by the energy-saving source bureau, and a response instruction is sent to the power users and the load integrator in the middle standard library through the Shandong power-saving demand side management platform to inform the response quantity and the response time period of the power users and the load integrator.

a transaction process for registration, declaration, response, evaluation, and settlement;
and responding according to the bid amount in the market at the day before by executing the response, wherein the response is used for receiving a calling instruction of the system.
Specifically, an economical demand response can improve market efficiency. When the elasticity of the demand side of the power market is smaller, part of marginal generator sets are easier to form market force, so that the market price rises suddenly. The demand response plays a crucial role in market force inhibition, and when demand response resources participate in market competition, a large number of new market main bodies (such as load integrators) are introduced to improve the market competition and weaken the market share of each power generation main body. The economic demand response is implemented in the power market, the market mechanism can be fully exerted, individual power generation enterprises are prevented from attempting to raise the electricity price in the peak period to earn high profits, and meanwhile, users also have more initiative and option rights to reduce the negative influence caused by price fluctuation.
The economic demand response user engages in a day-ahead transaction via a "volume quote" mode. The users are cleared to obtain electric energy income compensation, the economical demand response is determined by the users voluntarily whether to submit declaration information to an operation organization, and the late declaration, the missing declaration or the non-declaration persons are defaulted not to participate in the transaction. At the present stage, the economic demand response transaction and the current spot electric energy market are coordinated to run, and the daily real-time transaction is not carried out.

Setting the peak clipping response electric energy transaction effective evaluation price, and meeting the clearing condition when the average node electricity price at the power generation side of the spot market is higher than the evaluation price before the day, namely PAssessing price≤PHighest clearing price of issuing enterpriseThe clearing result is the response capacity of the operation day and the time-sharing clearing price of the spot market before the day. The evaluation price is a dynamic balance point reflecting the market supply and demand relationship, the operation organization can adjust in due time according to the power grid peak regulation gap, the new energy consumption condition and the like, the evaluation price is provided by the operation organization and confirmed after approval of government energy competent departments. The steps of the transaction process are:

before a second preset time, the demand load integrator declares the peak clipping response price, the response time period and the average response capacity per hour of the next day;
before a third preset time, the operation mechanism carries out demand response peak clipping transaction calculation based on the day-ahead electric energy transaction result, when clearing conditions are met, economic demand response peak clipping transaction is triggered, the operation mechanism calculates a transaction clearing result, and a user participating in economic peak clipping response is determined;
and before the fourth preset time, the operating organization issues an economic demand response peak clipping day-ahead trading clearing result of the operation day.

and secondly, before 12:00 of the D-1 bidding day, the demand response user declares the peak clipping response price, the response time period and the average response capacity per hour of the next day through a Shandong power-saving demand side management platform.
Thirdly, before D-1 bidding day 17:30, the operation organization carries out economic demand response peak clipping transaction calculation based on the day-ahead electric energy transaction result of the Shandong electric spot market, and when the average node electricity price at the power generation side of the spot market is higher than the effective evaluation price of the peak clipping response electric energy transaction at the current day, namely P isAssessing price≤PHighest clearing price of issuing enterpriseAnd triggering the economic demand response peak clipping transaction, calculating a transaction clearing result by an operating organization according to the principles of price priority, time priority and capacity priority, and determining the users participating in the economic peak clipping response.
And fourthly, before the D-1 bidding day is 18:30, the operating organization gives out the economic demand response trading clearing result before the peak clipping day on the operation day and issues the result through a Shandong demand side management platform according to related programs.
