In this study, a rule-based algorithm has been developed to optimally balance the grid frequency for the battery energy storage system (BESS), which is one of the most important sources of flexibility for electricity transmission and distribution networks and microgrids and is currently used to support the grid in many methods in developed countries. It is important to be able to control the net load since it is ensured that the net load is constant in the electrical grids and the grid frequency is constant. For this purpose, grid reliability is ensured by grid frequency support by making use of ancillary services of electricity system operators. A rule-based algorithm of a BESS system used to provide flexibility in ancillary services over the electricity grids of the UK and Turkey, and an algorithm that will provide ancillary service criteria by using real frequency data for both countries, by considering battery health in an optimum method, has been designed with MATLAB platform and the results of the simulation study have been interpreted. The difference between this study from the studies in the literature is that the optimum maximum and optimum minimum limits are determined in addition to the highest and lowest operating limits of the battery. The frequency support ancillary service between the limits defined in the grid codes and the results obtained are analyzed have been graphically demonstrated in both countries to be provided in the most appropriate manner and the results obtained are evaluated.
