Design of MGCC for user-side microgrid

As the microgrid control centers, microgrid central controller can achieve coordinated control of various equipment of microgrid and maintain safe, reliable and economic operation. So, it receives wide attention. A microgrid central controller is proposed in this paper for high reliability, low cost, generic, compact design. Microgrid central controller uses modular software and hardware design based on embedded system. The design reduces the costs of controller, and improves the portability of the controller. The paper also presents a general method based on profiles which enhanced controller for microgrid with different types and adaptability of equipment from different manufacturers. After preliminary testing, microgrid central controller has fully functional, stable and reliable operation.
