Development and Verification of Campus Microgrid Energy Management System

With the increasing requirement of the renewable energy integration and power system reliability improvement, the microgrid technology has achieved rapid development. Effective energy management is the solution to ensure the economic operation of microgrid. As the core equipment, the energy storage system can contribute to realizing the goal due to its capability of the energy shit over time and the power flow magnitude change. Therefore, the optimal energy storage system (ESS) scheduling is the essential application program. Moreover, the renewable energy generation and the electric load forecast are the other two necessary aforehand application programs. They can give out the forecasted system information to enable the ESS scheduling program to work out an optimal scheduling. In order to ensure the accurate running, the real time control is implemented to mitigate the effect of forecast uncertainty that is inevitable, benefitting from the supervisory control and data acquisition (SCADA) system. This paper aims to demonstrate the validity of proposed microgrid energy management system from the view of application programs based on a constructed campus microgrid.
