Abstract
Nowadays, renewable energy technologies, such as solar power and wind power, are trend to replace conventional energy resources. In the meantime, DC Microgrid is becoming popular in distribution systems due to the better compatibility and simpler system control strategy. This paper presents a hierarchical coordinated control strategy for DC Microgrid with wind turbine and photovoltaic array under various operating conditions to ensure reliable operation and provide voltage regulation via simulating equivalent model of DC Microgrid in PSCAD. The contents of this paper can be separated into two parts, the configuration of DC Microgrid and the control strategy. The configuration consists four components, AC grid, power generation unit, power consumption unit and battery energy storage system. The basic principle of those components will be introduced in detail in this paper. The proposal control strategy contains three control level for different objectives. The DC Microgrid model is demonstrated by using PSCAD/ETMDC and the simulation results are also presented to show the effectiveness of the control strategy.
