Research and Implementation of a Grid-Source Coordination Management Platform Based on Dispatching and Control Cloud

Abstract

Ultra-high voltage alternating current and direct current transmission in Zhejiang Province has experienced a rapid development in recent years., which poses a great challenge to the management of grid and source coordination. In this paper., an effective grid and source coordination management platform based on dispatching and control cloud is established to achieve the management and deepening utilization of grid and source coordination data., contributing to the operational safety of the Zhejiang power grid. Meanwhile., the information sharing of the provincial dispatching center and unified power plants can be realized through the platform., which can improve the efficiency of the grid and source coordination management. Several ultrahigh voltage grid DC blocking faults in the Zhejiang power grid were analyzed. The results show that the primary frequency regulation capacity of the Zhejiang power grid has been significantly improved after the effective strategies in the platform were implemented.
