With the rapid development of smart grid technology, end users are transitioning from a completely passive uncontrolled load to a controllable load that actively participates in the power market and system scheduling. And part of the power selling companies are transformed into power service providers with dual identities of energy consumption and production, and distributed renewable power sources, energy storage equipment, electric automobiles, controllable energy utilization equipment and the like on the user demand side are uniformly integrated and managed.
The electric power service provider predicts the output of the distributed power supply and the user load in advance, formulates competitive bidding electric quantity and power price, and participates in long-term transaction and spot transaction in the electric power market. Due to the fluctuation of the user load and the power of the distributed power supply, the competitive bidding electric quantity submitted to the trading center by the electric power service provider as an agent of the electric power user has deviation from the actual settlement electric quantity. Market managers have certain penalties for this deviation in order to operate the market more efficiently and to run the power system more reliably.
Currently, China is in a market mode of transition from medium-long term trading market to medium-long term trading and spot trading, spot trading trial is just developed in part of provinces and cities, and daily trading settlement is not realized. Most provinces, such as Hunan and Anhui, do not establish spot transactions, carry out medium-long term transactions of monthly settlement, and the electric quantity deviation settlement mechanism caused in months brings huge deviation punishment cost for electric power service providers. Therefore, the electric power service provider has important research significance for selecting a reasonable compensation strategy to effectively stimulate the controllable load to participate in the transaction by taking the benefit maximization of the electric quantity deviation penalty cost into consideration according to the load demand and the output uncertainty of the distributed power supply.
