Power System with high penetration of inverter based renewable generators have several problems such as voltage instability and frequency deviation. The most severe problems for such network is lack of inertia due to fewer number of synchronous generators connected to the grid. As portion of synchronous generators in network decrease, low inertia of system can be a major problem which hinder the additional renewable generator deployment. Energy Storage System (ESS) is adequate solution for this problems by providing inertia response and governor response to low inertia network. In this paper, actual network system study was conducted to integrate large wind farms in small network with low inertia. ESS and is installed at each point of interconnection of windfarms. Inertia response operation strategy of ESS is suggested to protect system from low frequency load shedding and also provide emergency reactive power compensation to prevent cascading failure of network due to voltage under fault ride through standard of wind turbines.
