Design and Application of Control System Based on DC Converter in Wind and Solar Hybrid Micro-grid

风光互补微电网中把分布式电源直接接入直流网络,降低了系统的控制要求,以便达到最大限度的对分布式能源的充分利用。在微电网系统中经过直流换流器接入直流网络,通过对常用的直流换流器分析比较,更好地节约电力电子器件,又能提高系统的安全和可靠性,仿真验证了直流换流器在微电网控制系统中的有效性与适用性,保证供电可靠性。

The direct access to the direct current network of distributed generation in the wind and solar hybrid microgrid reduces the control requirements of the system, so as to achieve the maximum utilization of distributed energy resources. In the micro grid system, DC network is joined up through the DC converter, and the frequently-used DC converter is analyzed and compared, so the power electronic devices is better saved, and the safety and reliability of the system is increased. The simulation verifies the validity and applicability of the DC converter in the micro-grid control system and ensures the reliability of power supply.
