Research on primary frequency regulation performance index system of new energy station

As the proportion of new energy sources such as wind power and photovoltaic in the power system gradually increases, the proportion of conventional synchronous generators gradually decreases, and the primary frequency regulation capability of the system changes. In this paper, the primary frequency modulation performance index system of new energy station is proposed, including static and dynamic indicators. The static indicators include adjustment rate, response time, adjustment accuracy and comprehensive adjustment performance, while the dynamic indicators include adjustment performance, input situation and index time scale.By designing the primary frequency regulation index system, a single-area simulation system including new energy is established, and simulation analysis is carried out to evaluate the performance of new energy stations in primary frequency regulation.
