摘要
现如今,分布式能源正在大规模布局并网,缓解能源需求与环保之间的矛盾。该文用Matlab对环境温度、光照强度、风速的变化进行了模拟,并在Simulink环境下搭建了风光储微电网的详细仿真模型,对光伏、风机以及蓄电池均采用有效控制策略。在仿真过程中,模拟了微电网运行中常见的几种状况,仿真结果显示,PCC母线交流侧的电压、频率、以及功率平衡都达到了实际的要求,验证了所搭建的风光储混合微电网仿真模型的正确性和有效性,为进一步完善仿真模型和开发控制策略提供了基础。
Nowadays,distributed energy is being grid-connected on a large scale to ease the contradiction between energy demand and environmental protection.In this paper,Matlab is used to simulate the changes of ambient temperature,light intensity and wind speed,and a detailed simulation model of wind/PV/storage hybrid microgrid is established under the environment of Simulink.Effective control strategies are applied to photovoltaic,wind turbine and battery.In the process of simulation,many common conditions in the operation of microgrid are included and simulated.The simulation results show that the voltage,frequency and power balance on the AC side of PCC bus meet the actual requirements.The correctness and validity of the micro-grid simulation control model provide the foundation for further improving the simulation model and developing the control strategy.
