摘要(Abstract):
针对含可控光伏主动配电网的日前调度问题,采用合适的功率控制策略使DC-DC变换器和DC-AC并网逆变器实现有功无功解耦控制。通过仿真探索计及有功可控能力的光伏发电系统的概率特性,得到有功参考值与其累积密度函数、均值之间的关系。进而考虑机会约束,设计能计算储能系统充放电次数的约束,建立以配网企业运行成本最小化为目标的有功无功协调的主动配电网日前优化调度模型。将非凸约束松弛,利用二阶锥规划方法求解确定性优化步骤,加入割集重复优化保证松弛为紧。结合基于随机响应面法的概率潮流方法检验机会约束,最终得到考虑光伏可控性的满足全部机会约束的效益最大化调度方案。算例结果验证了上述模型和算法是正确性的,且能够满足安全经济运行要求。
