摘要

提出一种光伏与可投切负荷的协调控制策略，利用光伏出力的可快速调节特性以及可投切负荷容量较大的特点，通过求解混合整数优化问题，确定各台光伏的实时参考出力以及各台可投切负荷的工作状态，并使用基于二次插值算法的功率控制策略，使各台光伏的出力快速跟踪其参考值，从而实现协调控制系统净出力的灵活可调。所设计的协调控制系统具有与传统混合储能系统类似的外部特性（如大功率的快速充放电），可为高渗透率的新能源电网提供必要的支持（如一次调频等）。此外，它还具有容量易于扩充、造价低廉等传统储能系统不具备的优势。基于微电网的仿真结果验证了该控制策略的可行性。

Abstract

A coordinated control strategy for photovoltaic systems（PVs）and controllable loads is proposed，with which the net power output of the coordinated control system can be flexibly adjusted and high-capacity characteristics of controllable loads can be used.By solving a mixed integer programming problem，the reference power output of PVs and operational conditions of controllable loads can be determined.With the quadratic interpolation based active power control strategy，each PV can track its reference power output，and the net power output power of the coordinated control system can be flexibly adjusted.Externally，the coordinated control system behaves like the conventional hybrid energy storage system，with characteristics such as the fast charging/discharging speed.In addition，it has such exclusive advantages as large capacity and low cost.The feasibility of the control strategy proposed is verified by simulation results.
