Generation Load Correlation in Power Grid Interconnected with RES

Integration of Distributed Energy Resources in conventional power grid have been a field of research and concern to enhance stability of the system. The work done is development of a Full-Scale "Comprehensive State-Space Model" for Micro-Grids consisting of Distributed Energy Resources (Inverter-based). All the sub-modules' model is combined together to achieve a "Comprehensive State-Space Model" of complete Micro-Grid as a whole. The system parameters and "Operating-conditions" are given as an input, to obtain eigen values on "MATLAB Software". Eigen values concept of Control theory is utilized to perform the small signal stability analysis by the way of monitoring displacement in the trace of eigen values which basically is indicating damping of oscillatory-components in transient conditions. Sensitivity-analysis is carried out to arrive at conclusions of what all modifications are demanded in the design of controllers such that system stability can be improved.
