Analysis of Primary Frequency Regulation Ability of Shandong Power Grid Thermal Power Unit

Abstract Shandong Power Grid is about to achieve the development goal of 30% of new energy power generation installed capacity, 30% of foreign power input into Shandong, and 30% of thermal power installed capacity. Neither new energy power generation nor external power has the ability to adjust primary frequency. Thermal power is the main force of primary frequency modulation of Shandong Power Grid. This article counts all primary frequency modulation remote tests of the Shandong Power Grid in 2020, analyzes the current status of Shandong Power Grid’s primary frequency modulation, gives an assessment method for the primary frequency modulation integral power, and summarizes three reasons for the unqualified primary frequency modulation. The reasons are analyzed separately, and optimization suggestions are given.
