In this paper estimation of PFC (Primary frequency control) reserves and their adequacy has been investigated. Since Pakistan is aiming to add more renewable generation to its power system to reduce their dependency on fossil fuels and because of their concern about the environmental polution. And this renewable penetration adds variability and complexity to the power grid and doesn’t add inertia to the system. So therefore overall inertia of the system decreases in result of addition of renewables. When the inertia of the system decreases, frequency deviations increases because of the renewable forecast error and other contingencies in the grid. To study thiese frequency deviations expected scenario for Pakistan power system are created for current and future Pakistan power system. From these studies, estimation of PFC reserves are made in this paper for future Pakistan power system. This paper also explain the frequency instability arises due to high renewable integration in power system and their feasible solutions for future Pakistan power system.
