Today, with the expansion of low-inertia technologies (such as wind power plants) or non-inertia technologies (such as photovoltaic power plants), the amount of network inertia and power related to the primary frequency response has decreased significantly. As a result, in the event of disturbances, the frequency changes with a relatively higher slope and the frequency may violate its permissible range. To solve this problem, several methods have been presented so far that create artificial inertia by power electronic converters connected to storage devices or renewable generation. Therefore, the models make the operation of these sources similar to traditional power plants and increase their contribution to the frequency response during storage contribution events. In this paper, the sensitivity analysis of energy storage contribution to providing inertia for the primary frequency response has been carried out. IEEE 3-bus and 118-bus networks are used as test networks. MATLAB software is also adopted for optimization. The results show the role of each of the storage parameters in the frequency response and how it is possible to meet the frequency response limitations of the network by managing the storage devices.
