摘要:
根据风能发电与太阳能发电的相辅特性以及蓄电池的储能特性,构建了一套多电源供电的直流微网系统发电模型.通过对此系统的能量流动及运行特性的分析,提出了此系统的能量管理方案.分别绘制出了直流微网各组成部分的模块方框图以及仿真模型.针对逆变器的拓扑结构得出了其控制的数学模型,采用基于SVPWM的电压电流双闭环控制实现了微网在并网和离网两种运行模式下的稳定运行和自动平滑切换.最后通过仿真测试验证了分布式电源、蓄电池、负载以及电网在不同的工况下此能源控制方案的可行性,实现了此供电系统的稳定运行.
Abstract:
This paper constructs a multiple power supply model of direct current micro grid system based on characteristics of the supplement between the wind and solar power generation and the battery storage of the direct current (DC) micro grid power system. And the paper also proposes solutions for the energy management of the system by analyzing the energy flowing and operating. In addition, the paper draws the module block diagrams and the simulation models of the DC micro grid components. Then the mathematical model is obtained according to the topology construction of the inverter. Besides, the stable operation and automatic smooth switch of the micro grid is achieved both in grid and off grid operation model by using the double closed loop control of the SVPWM based voltage and current. Finally, the feasibility of the energy controlling is verified by the simulation test under different working conditions such as distributed generation, the load and the power grid, realizing the stable operation of the system.
