摘要: |
提出一种基于自适应下垂控制的风光储微网调频控制方法。建立了风光储微网的系统模型,重点阐述了电池储能单元的三阶模型。基于储能电池的工作状态和充放电功率,确定了风电机组和光伏发电的动态出力策略。提出了一种自适应的下垂控制方法,即通过组网电源的功率裕度自适应调整各微源的下垂系数,充分发挥了微源的调节潜力和功率支撑能力。通过算例仿真验证了所提策略和方法的有效性。 |

Abstract: |
A frequency regulation method of wind-PV-ES hybrid micro-grid system based on adaptive droop control is proposed. Firstly, the wind-PV-ES hybrid micro-grid system model is established with giving the third-order model of energy storage. Dynamic output strategy of wind turbine and PV power generation is determined with considering the operating states, charge and discharge power of energy storage. The adaptive droop control method is proposed, which adjusts the droop coefficients of micro-source adaptively with considering power margins. The effectiveness of proposed method is demonstrated by case studies. |
