| Abstract: |
| According to the characteristics of micro-grid and distributed generation，the design，operation， optimization and control of micro-grid are discussed. With an engineering example，its design principle is pointed out：reliability，flexibility and power balance. Its configuration and operational modes are analyzed. The parallel mode，island mode and dual mode are described and their design characteristics are presented. Suggestions are made for the control system and optimized operation of micro-grid and distributed generation, and the overall concept of MEMS（Micro-grid Energy Management System） is proposed. Some issues，such as anti-island protection and short-circuit current，are explained. The solution of anti-island protection applying active and passive detections is submitted. |
