Abstract

The invention discloses a method for optimizing capacity configuration of a hybrid energy storage power supply in a renewable energy system. The method comprises the following steps: respectively establishing energy models of a wind generating set, a photovoltaic solar generating set, a storage battery and a super capacitor; establishing an optimization model of capacity configuration and corresponding constraint conditions according to the one-time investment cost of the hybrid energy storage power supply and the operation cost of the whole life cycle; based on a multiplication and division optimization method, establishing an objective function for minimizing the total cost and corresponding constraint conditions according to a hybrid energy storage power supply capacity configuration optimization model; according to constraint conditions of the objective function, solving the objective function by adopting a differential evolution algorithm to respectively obtain the minimum valuesof the one-time investment cost and the full life cycle operation cost; the optimization of the capacity configuration of the hybrid energy storage power supply is realized, and the one-time investment cost and the operation cost of the whole life cycle are greatly reduced while the utilization of wind energy and photovoltaic solar energy resources is maximized on the premise that the load requirement is met.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an optimization method for capacity allocation of hybrid energy storage power sources in a renewable energy system. Background technique [0002] With the rapid depletion of traditional oil resources and the increasing global warming, researchers and scientists around the world are trying their best to find green alternative energy sources. Renewable energy systems composed of wind energy and photovoltaic solar energy have become a research hotspot. However, both wind energy and photovoltaic solar energy are intermittent, and in order to ensure the stability and reliability of energy supply, it is usually necessary to set up a suitable energy storage system in the renewable energy system. Generally, batteries are used for energy storage in small and medium-sized power generation systems composed of wind energy and photovoltaic solar energy. However, the energy storage power su...
