Optimization Model of Short-Term Positive Deviation Electricity Assessment of Power Selling Companies Considering Incentive Demand Response

In the early stage of the establishment of the spot market, the short-term assessment mechanism with the day as the settlement period is conducive to fair trading in the market and stabilizing the power balance. Under the daily deviation assessment mechanism, this paper constructs the day ahead market income model of power selling companies, and analyzes the impact of short-term deviation assessment on the income and business strategy of power selling companies. At the same time, in order to better correct the deviation assessment electricity and reduce the penalty cost of power selling companies, the incentive demand response is taken as an important tool for power selling companies to deal with the spot market risk and correct the deviation electricity, and the incentive demand response master-slave game model between a single power selling company and multiple power users is constructed. The power selling company reduces the power selling loss by formulating the demand response compensation strategy, and the power user determines the response in the corresponding period according to the compensation price specified by the power selling company, so as to obtain income and save power cost. The analysis shows that the optimization strategy can effectively avoid the risk of spot market, correct the deviation electricity, and improve the income of power selling companies and power users.
