摘要
交直流混合电力系统优化配置过程会受到光伏、风机出力不确定性的影响,电力系统规划效果较差,由此,设计一个交直流混合电力系统中长期双层优化配置规划方法。将二元变量模型引入不确定模型中,计算风、光资源对交直流混合微电网优化配置的影响参数,计算交直流电力系统潮流,设置目标函数与系统功率条件,进行容量优化,实现交直流混合电力系统中长期双层优化配置规划。实验结果表明,所提出的规划方法提高了电压相角区间估计精度、电压幅值,还降低了换流损耗与规划成本,满足实际设计需求。
The optimal configuration process of the AC-DC hybrid power system will be affected by the output uncertainty of photovoltaics and wind turbines,and the power system planning effect is poor.Therefore,a medium-and long-term double-layer optimal configuration planning method for the AC-DC hybrid power system is designed.We will introduce the binary variable model into the uncertainty model,calculate the influence parameters of wind and light resources on the optimal configuration of the AC-DC hybrid microgrid,calculate the power flow of the AC-DC power system,set the objective function and system power conditions,perform capacity optimization,and realize AC-DC power flow.The experimental results show that the proposed planning method improves the estimation accuracy of the voltage phase angle interval and the voltage amplitude,and also reduces the commutation loss and planning cost,and meets the actual design requirements.
