摘要
集中式控制方法难以满足未来电网分布式电源大量接入以及即插即用的技术要求。为进一步提升分布式控制方法的实用性,提出一种基于连续时间投影梯度算法的分布式电源功率协同控制方法。相比于目前基于一致性算法的控制方法,所提控制方法不需要假设系统负荷总量已知,不用人为设计算法初值,仅利用投影算子对分布式电源出力进行约束,即可自动运行到经济调度的最优点,显著提高了分布式控制方法的实用性。最后,算例验证了所提方法的有效性。
Centralized control method can hardly meet the technical requirements of large-scale access and plug-and-play of distributed generation in the future power grid.To enhance the practicability of distributed control method,a power cooperative control method for distributed generation based on continue-time projected gradient algorithm is proposed.Compared with the consensus-based control method at present,the proposed control method does not need to assume that the total load of the system is known and design the artificial initial value but only uses the projection operator to constrain the output of the distributed generation,which can automatically run to the optimal point of the economic dispatch,thus significantly improves the practicability of distributed control method.The case study is given to verify the effectiveness of the proposed method.
