摘要:

随着电力系统规模的日益扩大和可再生能源渗透率的不断提高,风电作为清洁能源的重要组成部分,在电网频率调节中扮演着越来越重要的角色。由于风电的波动性和间歇性,传统的电网调频策略面临新的挑战。针对这一问题,分析了储能虚拟同步调频控制策略,深入研究了风-储联合一次调频控制技术,采用基于变系数bang-bang控制的惯量响应自适应控制方法优化调频功率分配,提出了一种基于中间层的风-储一体化调频控制策略,通过分层管理实现更高效的控制。仿真结果表明,该调频控制策略在电网频率波动时能够有效调节电网频率,减少频率偏差,实现了风电场和储能系统在电网频率变化时的优化调频功率分配,提高了电力系统的稳定性和可靠性。

Abstract:

With the continuous expansion of power grids and increasing penetration of renewable energy, wind power, as a key component of clean energy, plays an increasingly important role in power grid frequency regulation. However, the volatility and intermittency of wind power pose new challenges to traditional grid frequency regulation strategies. To address this issue, the strategy of energy storage-based virtual synchronous frequency regulation was analyzed, with an in-depth investigation of wind-storage integrated primary frequency regulation control technology. An adaptive inertia response control method, based on variable coefficient bang-bang control, was employed to optimize the allocation of frequency regulation power. A wind-storage integrated frequency regulation control strategy based on intermediate layer was proposed to achieve more efficient control through hierarchical management. The simulation results showed that the proposed strategy effectively regulated grid frequency during fluctuations and reduced frequency deviations. It optimized the allocation of frequency regulation power between wind farm and energy storage system during changes in grid frequency, significantly enhancing the stability and reliability of the power system.
