The invention relates to an electricity purchasing method and system for an electricity selling company under a spot transaction mechanism, and the method comprises the steps: firstly calculating theelectricity purchasing and selling cost of the electricity selling company, and calculating the actual revenue of the electricity selling transaction of the electricity selling company after the loadadjustment; calculating a risk measurement index as a transaction risk of the electricity selling company; and finally, constructing and solving an electricity purchasing optimization decision model taking electricity purchasing decision optimization of the electricity selling company as a target, and carrying out electricity purchasing according to the obtained solution. According to the invention, an operation mode and risk analysis of an electricity selling company are used; an electricity purchasing optimization decision model of the electricity selling company is constructed by taking theprofit of the electricity selling company and the satisfaction degree of the user as targets; an adaptive mutation improved multi-objective differential evolution algorithm is adopted for model solving. According to the method, the evolution direction of the algorithm is improved, the reservation sorting of non-occupied solutions is realized, the expected transaction electric quantity of the electricity selling company in different electricity purchasing sources is obtained, the electricity selling company can better adapt to the market environment, the market initiative is won, and the maximization of the multi-agent benefits of the market can be realized.
Description
technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to a method and system for purchasing electricity of an electricity selling company under a spot transaction mechanism. Background technique [0002] The modern power market system is composed of medium and long-term trading market and power spot trading market. As far as medium and long-term electricity trading is concerned, at this stage, various provinces, cities and regions in my country have initially formed medium- and long-term trading mechanisms with complete functions, while the construction of the spot market is still in its infancy and is planned to be fully launched by the end of 2020. To this end, it is necessary to further accelerate the exploration of the power spot trading mechanism, change the original market operation mode, improve the market-oriented power balance mechanism, gradually form a medium- and long-term power trading model that...
