Abstract

The present application relates to a micro-grid energy storage optimal configuration method and device in consideration of full life cycle cost. The micro-grid energy storage optimal configuration method in consideration of full life cycle cost includes: obtaining the data of an energy storage system to be configured to obtain target data; obtaining a pre-established energy storage optimization model, the energy storage optimization model including an outer layer optimization model and an inner layer optimization model; based on the target data, obtaining the optimal solution of the energy storage optimization model by a genetic algorithm and a simulated annealing algorithm so as to obtain an optimal configuration result, wherein the optimal configuration result at least includes the ratedpower, the rated capacity and the economic operating power; and configuring the energy storage system to be configured according to the optimal configuration result. The method provided by the present application can minimize the cost and maximize the benefits of the energy storage system during the full life cycle.

Description

technical field [0001] The present application relates to the technical field of microgrid energy storage, and in particular, to a method and device for optimizing the configuration of microgrid energy storage that takes into account the full life cycle cost. Background technique [0002] With the increasingly prominent problems of energy crisis and environmental pollution, distributed generation (DG) grid-connected power generation has become an important research direction of the power industry in the 21st century. The large-scale access of distributed generation to the grid has produced a series of impacts on the voltage, power quality, dispatch and operation of the grid. Energy Storage System (ESS), as an important part of microgrid, can effectively solve these problems and maintain the stability of the grid. [0003] At present, the main obstacles to the large-scale application of energy storage systems are relatively low service life and high cost. Therefore, the opt...
