Design a novel controller for stability analysis of microgrid by managing controllable load using load shaving and load shifting techniques; and optimizing cost analysis for energy storage system

System stability is one of the most imperative requirements in a Microgrid designing to have an efficient, secure, and sustainable performance using renewable energy sources. In this paper, as a cardinal objective, the voltage and frequency stability is achieved by power balancing technique using load shaving and load shifting method. In particular on this occasion, controllable load is the only manageable load by which we can optimize cost using those two techniques and therefore the cost can be greatly reduced; thus saving substantial amounts of money to reduce electrical power consumption during peak/mid-peak hours. Moreover, the capacity of designed power system can be optimized by the same token. This paper proposes a novel controller to handle the frequency and voltage stability based on the generation and load; it can also track down the optimal cost line to facilitate the entire distribution policy. An energy storage system has also been proposed to manage those peak hours/loads in case of insufficient/surplus of the net generation and sub-sequential cost analysis has been presented as well. The feasibility of this method has been authenticated very meticulously by Matlab/Simulink verification.
