Abstract

The embodiment of the present application provides a multi-time-scale coordinated control method for an island microgrid, and proposes a multi-time-scale coordinated control method that includes a day-ahead output plan curve, an intraday rolling optimal dispatch plan curve, and fast real-time coordinated control. For the short-term power prediction results of the second time scale, the preset intraday rolling optimization model is used to more accurately adjust the output planning curves of various distributed power sources, and finally according to the difference between the real-time net load power data and the theoretical net load power data Notify the preset multi-energy complementary real-time coordinated control strategy to issue control commands to each distributed power supply, further improve the robustness of the system, give full play to the complementary advantages of the hybrid energy storage system, and solve the problem of not using the complementary characteristics of hybrid energy storage Considering the coordinated control of multiple time scales comprehensively, the resulting control accuracy is not high enough, and the control effect has not achieved the optimal technical problem.

Description

technical field [0001] The present application relates to the technical field of power control, in particular to a multi-time-scale coordinated control method for an island microgrid. Background technique [0002] Microgrid is a small power generation and distribution system that integrates micro power sources, loads, and power electronic devices. It is an effective way to increase the utilization and penetration of renewable energy, improve energy structure, and reduce environmental pollution. The island microgrid is an independent microgrid. Due to the special geographical conditions of the island and the demand for electric energy, the operation technology of the island microgrid with multiple energy complementary power generation has been applied in the construction of the island power grid since it was proposed. Formulating a scientific and effective coordinated control strategy is an important link to ensure the safe, stable and economical operation of an independent m...
