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.
