摘要
针对边防哨所的特殊性,以及风力发电和太阳能发电所存在的随机性、季节性和间歇性而引发的微电网系统的电压波动、功率波动等问题。为了维持微电网系统的电压、功率的输出稳定,保证微电网的稳定运行。通过以风光互补发电为形式的方法解决供电不稳定,并增加以铅蓄电池和热水为介质的混合储能单元,储能系统吸收和释放发电单元侧和负载侧之间的功率差值来平抑微电网的能量波动。在MATLAB/Simulink上建立带混合储能单元的微电网供电系统仿真模型,得到风力发电机、太阳能光伏阵列及储能装置的功率变化曲线,从而验证了混合储能控制策略的可行性。
Aiming at the particularity of border guard posts,as well as the randomness,seasonal and intermittent of wind power generation and solar power generation,the voltage fluctuation and power fluctuation of micro-grid system caused by wind power and solar power generation were analyzed. In order to maintain the stability of the voltage and power output of the micro-grid,the stable operation of the micro-grid was ensured. The wind-pv hybrid generation was used to complement the unstable power supply,and the lead battery and hot water were increased for the hybrid storage medium unit. The storage energy absorbs and releases the power difference between the unit side and load side to stabilize the energy fluctuation of micro-grid. A micro grid simulation model of electric power system with hybrid energy storage unit was established based on MATLAB/Simulink,to get the power curve of wind turbine,solar photovoltaic array and storage device,which verifies the feasibility of the control strategy of hybrid energy storage.
