Day-ahead energy management of a microgrid with renewable energy resources and CHP units, considering demand response

Global warming, environmental pollution, fossil resources reduction, the increased demand and price of energy carriers, and various international social and political consequences are among the problems of traditional energy generation and distribution system. In the traditional generation systems, about two-thirds of energy is wasted and the presence of scattered energy resources such as photovoltaics, wind farms, and the simultaneous generation of power and heat can lead to the reduction of fuel consumption and losses, and the high efficiency of micro-grids. This is not realized except by changing energy consumption policies and using the privatization potential for energy production, transmission, and distribution. In this research, the 24-hour energy management optimization of a micro grid, including scattered photovoltaic and wind energy resources, was investigated by complying with uncertainty and the simultaneous generation of power and heat beside demand response program in a 33-bus micro grid connected to the main grid. The obtained results show that by implementing demand response program when the power and heat sources are switched on simultaneously, the micro grid has earned a profit of 70% during the year, and in addition to saving energy and reducing the cost of consumers, the use of such units beside each other has caused a reduction in the power outage, and led to appropriate demand response, and consequently, satisfaction of the power and heat customers.
