【摘要】：对于电网建设困难、风资源却比较丰富的地区,风柴蓄微电网是解决其供电问题的一个有效手段,既可以充分利用当地的自然资源,又可以保护环境、减少投资运行成本。介绍了风柴蓄微电网风力发电系统、柴油发电系统和蓄电池储能系统的结构及工作原理,建立了各子系统的详细数学模型,在Matlab/Simulink中搭建各子系统模型并进行仿真,仿真结果表明搭建的模型能够较好的反应各电源的特性。以受控电压源模拟可控负载,实现了蓄电池充放电控制仿真。在Matlab/Simulink中的仿真表明,该模型能够仿真蓄电池在允许的最大充放电能力内跟踪富余功率进行充电,跟踪缺额功率进行放电,在超出最大充放电能力时以最大充电能力进行充电,以最大放电能力进行放电。以蓄电池充放电控制仿真模型为基础,建立风柴蓄微电网的能量管理仿真模型,对风柴蓄微电网的供电状况进行仿真。该能量管理仿真模型能够对不同能量管理策略下微电网内资源的调度情况进行仿真,还可以对系统容量配置进行设计和校核。
[Abstract]:With the difficulty of grid construction and abundant wind resources , the wind - wood - storage micro - grid is an effective means to solve the problem of power supply , which can not only make full use of local natural resources , but also protect the environment and reduce the cost of investment operation .

This paper introduces the structure and working principle of wind power generation system , diesel power generation system and storage battery energy storage system of wind - wood storage micro - grid , establishes the detailed mathematical model of each sub - system , sets up each sub - system model in Matlab / Simulink , and simulates . The simulation results show that the built model can better reflect the characteristics of each power supply .

The simulation of charge and discharge control is realized by simulating controllable load by controlled voltage source . The simulation in Matlab / Simulink shows that the model can simulate the maximum charge and discharge capacity of the battery for charging and tracking the power supply to discharge . When the maximum charge - discharge capacity exceeds the maximum charge - discharge capacity , the maximum charging capacity is charged , and the maximum discharge capacity is discharged .

Based on the simulation model of battery charge and discharge control , the energy management simulation model of the wind - wood - storage micro - grid is established , and the power supply condition of the wind - wood - storage micro - grid is simulated . The energy management simulation model can simulate the dispatching situation of resources in the micro - grid under different energy management strategies , and also can design and check the system capacity configuration .
