Integrated Energy Management of Micro-Grid using Multi Agent System

The objective of this paper is to develop a Multi Agent System (MAS) for the integrated energy management of a solar micro-grid. We consider a grid connected solar micro-grid which contains two solar Photo Voltaic (PV) systems each contains a local consumer, a solar PV system and a battery. First we calculate the load patterns and solar power generated in the two solar units. Then we use Multi Agent System based distributed energy management of solar micro-grid with smart grid frame work. We develop a simulation model in Java Agent Development Environment (JADE) for dynamic model which considers the intermittent nature of solar power, randomness of load, dynamic pricing of grid and variation of critical loads and choose the best possible action every hour to stabilize and optimize the solar micro-grid. Further more, MAS increases the operational efficiency and thereby maximizes the power production of solar micro-grid and minimizes the operational cost. Thus MAS in micro-grid leads to economic and environmental optimization. Simulated operation of solar generators and loads are studied by performing simulations under different agent objectives. Outcome of the simulation studies demonstrates the effectiveness of proposed MAS in distributed energy management of micro-grid.
