Energy management changes the electricity consumption pattern of customers. This change is done to achieve the optimal consumption curve. Using energy management, by reducing consumption in periods, besides the appropriate load curve, it reduces the cost of operation and planning. Electricity supply in traditional networks is done by large power plants that are concentrated in certain places. The generated energy must be transferred to consumption points by transmission and distribution networks. The above-mentioned power system has many problems, among which we can mention the decrease in reliability and availability due to the wear and tear of the electrical system infrastructures and the imposition of high costs of losses in the energy transmission to the load points. In other words, management includes a set of activities that affect the pattern and amount of consumer load. Basically, consumption management programs aim to achieve various goals, the most important of which are improving the efficiency of energy systems, increasing the load factor, reducing the need for investment to build and postponing the construction of new power plants, reducing the effects harming the environment, reducing the cost of electricity supply to customers, compensating for the shortage of supply and reducing the excess demand for electricity, improving the reliability and quality of power, promoting the development of energy economy, creating a culture of saving and effective support for customers pointed out.
