Optimization of Reserve Capacity for New Energy Participating in Primary Frequency Regulation of the Power System

The frequency regulation problem of the power system under the scenario of a high proportion of new energy access has attracted attention. It has become an important technical means for new energy to reserve a certain amount to participate in system frequency regulation. Reserve capacity, response speed, and regulation rate jointly determine the post-disturbance frequency trajectory of the system. This paper briefly compares the primary frequency regulation control performances of wind power generation, photovoltaic power generation and thermal power generation, analyzes the influence of factors such as frequency distribution, regulation rate, frequency regulation capacity and frequency deviation on primary frequency regulation, and, considering the need for rapid frequency response in power systems with a high share of new energy, taking into account the system frequency response performance and new energy consumption demand, a method for optimizing the reserve configuration of new energy power generation for primary frequency regulation is proposed. Simulation analysis is carried out using a simplified actual power system, and the results show that an appropriate reserve provided by new energy helps the system frequency recover quickly.
