Calculation method for frequency regulation parameter requirements of power systems based on active reserve of renewable energy

Abstract The integration of inverter-based power sources has exacerbated the issue of power system frequency stability and placed increasingly higher demands on the frequency support capabilities of inverter-based power sources clusters. This paper proposes a calculation method for frequency regulation parameter requirements of power systems based on active reserve of inverter-based power sources. It establishes a discretized power system frequency response model using the forward difference method. Furthermore, based on active reserve of inverter-based power sources, an optimization model is constructed using multi-objective function optimization to obtain the calculation results for frequency regulation parameter requirements of power systems. This method aids system dispatchers and renewable energy stations in realtime assessment of power system frequency security levels and guides the adjustment of various frequency regulation parameters for renewable energy, ensuring the safety of power system operation.
