Micro-grid Grid Outage Management Using Multi-agent Systems

The objective of this paper is to develop a Multi Agent System (MAS) for Outage Management in electrical energy management of a micro-grid. We consider a grid associated micro-grid which contains two systems each contains solar Photo Voltaic (PV) system, wind system, a local consumer, and a battery. First we calculate the load trends and solar and wind power produced in the two solar units. Then we go on to implement grid outage management using Multi Agent System based distributed energy management of solar micro-grid with smart grid structure. We develop a simulation model in Java Agent Development Environment (JADE) for dynamic model which takes into account the closely knit nature of solar power, impermanence of load, dynamic appraising of grid and variation of critical loads and choose the best possible action every hour to stabilize and optimize the micro-grid. Furthermore, MAS increases the functional efficiency and thereby maximize the power production of solar micro-grid and minimizes the operational cost. Thus MAS in micro-grid leads to optimization of both capital and environmental resources. Simulated working of solar generators and loads are studied by conducting simulations for different agent motives. Simulation studies shows the balancing of micro-grid during the grid outage.
