Future of gas engines and micro grids12/2/2023 ・ The small Microgrid can produce power of 5 - 10 MW to serve the customers ・ Small Microgrid covers 30 - 50 km radius The followings are parameters of Microgrid: Produced heat from gen-Įration sources such as microturbines could be used for local process heating or space heating, allowing flexible tradeoff between the needs for heat and electric power. These multiple different electric power supply generation resources have ability to isolate the Microgrid from a large network and will provide highly reliable electric power. In Microgrid generation resources can include such as fuel cells, wind, solar, or other energy sources as shown in Figure 1. In the past, there was single entity to control. But one issue related to Microgrid is that operator should be very vigilant because numbers of power system are connected to Microgrid. Generation and loads in a Microgrid are usually interconnected at low voltage. The Microgrid can then function autonomously. The main benefit of Microgrid is that it can operate in standalone mode or main grid disconnection mode. Microgrid can operate in two modes: one is grid-connected and the other is stand-alone mode. These are integrated for electricity generation, energy storage, and a load that normally operates connected to a main grid (macro grid). The main components of Microgrid are mini-hydro, solar cell, wind energy, fuel cell and energy storage system. Microgrid, Diesel Engine, Fuel Cell, Microturbines, Wind Turbine, Photovoltaic, Genetic Algorithms Finally a complete model built of Microgrid including the power sources, their power electronics, and a load and mains model in MATLAB/Simulink is presented. Current models of a fuel cell, microturbines, wind turbine and solar cell have been discussed. In this paper, model of Microgrids with steady state and their transient responses to changing inputs are presented. Some models exist which describe the components of a Microgrid. Not much is known about Microgrid behavior as a whole system. The Microgrid concept assumes a cluster of loads and micro sources operating as a single controllable system that provides both power and heat to its local area. Microgrid is a new concept in power generation.
