The invention relates to the technical field of
electricity transaction management, in particular to an
electricity transaction retail
package optimization method and
system, and the method comprises the steps: constructing an
electricity selling company cost measurement and calculation model to calculate a monthly cost measurement and calculation price, and setting the monthly cost measurement and calculation price as a
package pricing cost
base line; establishing an objective function of
package optimization by taking the revenue maximization of the electricity selling company as an objective, and forming an initial optimization model; a compliance package optimization model is formed by loading preset package constraint conditions; solving the compliance package optimization model by adopting an intelligent optimization
algorithm, ensuring that the solved package price is higher than the cost
base line, and outputting an optimal package solution; the optimal package solution comprises a scheme for dividing peak, flat and valley time periods of all moments generated every month, and electricity prices which correspond to all the time periods and conform to the package price multiple rule. The problems that an existing package mode is low in efficiency, low in customer satisfaction and unstable in income, and market contradictions are likely to be caused are solved.
