摘要
微电网运行经济性是制约其商业化运营的主要因素,通过对其进行有效评价以获取降低成本的方法将成为解决这一问题的有效途径。通过对微电网运行成本进行分析,以微电网经济运行为基础,兼顾电网备用成本,提出了针对不同容量的微电网运行经济性评价指标。基于所提评价指标,对储能容量、储能价格、电价及能量管理策略等因素影响微电网经济性运行的作用进行了评价,最后结合示范工程运行数据,以实例验证了所提评价方法的有效性。
The operation economy of micro grid is the main obstacle of its commercial operation.An effective way to solve this problem is the evaluation and the cost reduction from the evaluation.Through the analysis on the operating cost of micro grid,this paper proposed the evaluation index of operation economy for the micro grids with different generating capacities,with considering the standby cost of grid,based on the economic operation of micro grid.On the basis of this evaluation index,the influence of energy storage capacity and price,electricity price and energy management strategy on the operation economy of micro grid was studied.Finally,the operation data from demonstration project was used to validate the effectiveness of evaluation method.
