Optimal Day-Ahead Scheduling for Campus Microgrid by Using MILP Approach /

Abstract

Micro-grid (MG) provides the promising solution with the help of renewable energy resources (RER), energy storage system and distribution system (DGs) for expansion and advancement of such distribution network which is complex, unfeasible, ecounfriendly, uneconomical and has high power loss. This thesis deals with energy management system (EMS). In this research work , energy management system (EMS) is proposed for institution which helps in reducing the operational cost with the help of using different distributed generators (DGs) and electric vehicles. For this purpose, a scenario is created in which university is connected with national grid having self-powered PV plant, electric vehicles and a diesel generator. Impact of various distributed generators and optimally scheduled energy storage system (ESS) are analyzed for the university campus which helps in reducing operational cost of energy by using campus load data. The proposed model consist of different distributed generators and their effects are observed in various scenarios. Mix Integer linear programming (MILP) is used to get optimized result and then it is compared with Ant Colony Optimization and Linear programming (LP) techniques. Economic and environmental benefits are also discussed. Operational cost was measured and compared and found the role of ESS by using MILP in minimizing operational cost from $798.560 to $756.3850.
