A multi-market coupled optical storage charging micro-grid system adjustable capacity optimization method, computer program product and optical storage charging micro-grid system

Abstract

This invention provides a method, computer program product, and a photovoltaic-storage-charging microgrid system considering multi-market coupling for adjusting its adjustability. The method includes: calculating a load baseline to characterize the charging service capacity of the photovoltaic-storage-charging microgrid system; calculating the adjustability of the photovoltaic-storage-charging microgrid system in the demand response market; calculating an optimal charging service strategy with the maximum adjustable charging service capacity within a charging service transaction day as the optimization objective, and calculating an optimal demand response strategy with the maximum adjustable demand response capacity within a demand response transaction day as the optimization objective; converting the two strategy calculations into an optimization calculation with the maximum sum of the adjustable charging service capacity and the adjustable demand response capacity as the objective, incorporating the sum into the constraints of the optimization calculation according to the definition of the Minkowski sum, obtaining a feasible solution set for the optimization calculation, solving it, and outputting the adjustability for each time period based on the solution results.
