摘要(Abstract):
随着风电、光伏等可再生能源接入比例的升高,使得配电网运行和控制面临着巨大挑战。综合考虑风光储模型,并计及了风光荷的不确定性、风速与光照强度预测误差的相关性,结合多项式正态变换方法(three-order polynomial normal transform,TPNT)、拉丁超立方采样(Latin hypercube sampling,LHS)技术产生样本,并基于同步回代缩减法(synchronous back reduction,SBR)进行场景缩减,建立了基于场景法配电网有功–无功协调优化模型。利用二阶锥松弛(second order cone relaxation,SOCR)技术和大M等方法,将原始模型,即混合整数非线性非凸(mixed integer nonlinear programming,MINLP)模型,转换为混合整数二阶锥规划(mixed integer second-order cone programming,MISOCP)模型,可直接调用MOSEK求解器求解。在改进的IEEE 33配电系统上进行算例仿真,验证了所提方法的精确性、合理性。
