Incentive calculation method of virtual power plant system based on user-side unilateral bidding

Abstract

The incentive calculation method of the virtual power plant system based on the user side unilateral bidding comprises the process of carrying out compensation settlement on a user executing responseof a demand side: calculating a single response quantity coefficient, and carrying out response quantity compensation price adjustment based on a response quantity proportion; calculating a single response speed coefficient, and adjusting a response speed compensation price based on the response speed; determining a single response duration; and determining the annual response subsidy according tothe single response coefficient, the annual response participation coefficient, the annual response release coefficient, the user contract response quantity, the unified clearing price, the demand side response annual release frequency and the like. When the regional load is accurately adjusted based on the virtual power plant technology, incentive and reward and punishment settlement can be carried out according to the actual response quantity of the participants.

Description

technical field [0001] The invention relates to an incentive calculation method for a virtual power plant system based on unilateral bidding at the user side. Background technique [0002] In the power system, power generation and power consumption are almost completed at the same time. In addition to power generation, the power plant also needs to generate more electricity according to the peak period of electricity demand and less electricity during the trough period to ensure the balance between supply and demand of the power grid. With the development of economy and society, the peak-valley difference of urban power grids is getting bigger and bigger. However, if we blindly expand power plants to meet the electricity demand during peak hours, huge waste will be generated during low-peak periods. Therefore, how to reduce the peak-to-valley difference more economically and efficiently has become one of the important issues of the urban power grid. [0003] Virtual power p...

Problems solved by technology

However, there are still some problems in the participation of virtual power plants in market bidding. First, how to reasonably dispatch a large number of customers in virtual power plants, and how to reward and punish responding users on the basis of satisfying their own loads to enhance their participation in demand response positive, and then realize the maximization of benefits through the cooperative game of internal resources; second, there are many types of internal resources in virtual power plants, especially when there are uncertain wind power, photovoltaic and other subjects, they are often not directly equivalent to traditional power generating units. In the process of considering the virtual power plant bidding process, it is necessary to consider the treatment of uncertain factors, and settle the settlement based on the actual response of the user to achieve fairness and justice

In addition, in the unilateral power market model, due to the lack of a user-side market, the price elasticity of power loads in the market is negligible, and it is difficult to avoid the problem of power generators taking speculative means to drive up power prices
