Micro-Grid: Techno-Economic-Greener Solution for Power Distribution System

Centralized power systems are providing way to massive number of distributed generation and energy storage system in micro-grid. Technical, environmental and economic obligation are alternating the trends of electricity generation and transmissions. Renewable energy sources are considered as important preference in micro-grid. Simulation results by HOMER shows a case study of an optimal contour of micro grid with solar energy, diesel generators and energy storage system at a site, Ranchi. For different cases including a base case (main grid and diesel generators) and micro-grid case (main grid, solar energy, diesel generators and energy storage system) are simulated and compared. The main focus of the system is on the optimal design and scheduled operation of micro-grid to maximize usage of green energy, reduction of environmental emissions and decrement of levelized cost of electricity.
