Optimization allocation of energy storage for microgrid based on economic dispatch
摘要
Abstract
For the uncertainties of renewable energy generation and load, energy storage device plays an important role in ensuring the safe and reliable operation of microgrid system. To accurately analyze the scheme of optimal allocation of energy storage for microgrid which contains various distributed generations, optimization allocation model of energy storage for CHP microgrid based on economic dispatch and heating income is established. A quantitative analysis method for allocating the minimum storage capacity in grid-connected and islanded modes is presented. A microgrid consisting of a wind turbine, photovoltaic cells, a storage battery, a micro turbine, a fuel cell, heating and electric loads is selected as the research object. The improved genetic algorithm is chosen to optimize the output of microsources, and electricity purchases and sales between external network and microgrid. The storage capacities for achieving the minimum comprehensive cost are determined in two operation modes. The validity of the proposed model, dispatch strategy and algorithm is proved by the examples.关键词
