摘要
小区中引入微网技术,在一定程度上减少了大电网的供电压力。为改善小区微网的经济调度能力,并考虑各类分布式电源对小区微网的影响,建立了并网运行时以微网发电成本最小和孤岛运行时以微网综合效益最大为目标函数的优化模型。采用高斯粒子群优化算法对模型进行优化求解,并与采用标准粒子群优化算法的优化结果进行对比。结果显示,高斯粒子群优化算法确保可以更好地提高小区微网的经济性。
Micro-grid technology is integrated into residential areas,to a certain extent,reducing the supply pressure of large power grid.In order to improve the economic load dispatching of the micro-grid,the optimization model with the goal of minimizing the generating cost during grid connected operation and maximizing the economic benefits during islanding operation was built up in consideration of the influence of kinds of distributed power on the micro-grid.Modified particle swarm optimization algorithm was used to optimize the model,and compared with the optimized result of the standard algorithm.The results show that the modified algorithm can better ensure the economy of the residential areas micro-grid.
