飞轮阵列参与电网一次调频双层控制策略
The flywheel array participates in a two-layer control strategy for primary frequency modulation of the power grid
摘要
Abstract
The large-scale integration of new energy sources into the power grid has led to increased frequency fluctuations,posing challenges to system stability.The participation of a flywheel energy storage array in primary frequency regulation can effectively enhance frequency stability and improve grid security.To address power distribution within the flywheel energy storage system and among individual units in the array,a two-layer control strategy is proposed.This strategy considers flywheel array losses,reduces system frequency deviation,and mitigates output fluctuations in thermal power units.The upper-layer control incorporates a dynamic droop-inertia coordinated strategy.A mathematical model is developed to quantify flywheel array losses,and an inequality constraint on flywheel output is established using the Logistic function.The particle swarm optimization algorithm is employed to determine the optimal power distribution among flywheel units,ensuring system requirements are met while minimizing overall power losses.Simulation results demonstrate that the proposed control strategy enhances system frequency stability,reduces wear on thermal power units,and lowers the power losses of the flywheel array.关键词
