MODELS OF ELECTRICAL POWER MANAGEMENT IN APPLICATION OF ENERGY CONSERVATION BASED ON THE ENVIRONMENT.

Utilization of conventional electrical energy as the fulfillment of living necessities for lighting and electrical equipment is increasing, which can cause problems in the provision of electrical energy. Energy management is needed to solve the problem of energy utilization, especially the problem of energy demand during peak load. The greatest energy consumption during peak loads is for building lighting at night, including street lighting. The use of electrical energy for the national public road lighting is getting bigger due to the increase in the length of national roads each year significantly. In North Sumatera Province, by the end of 2019 the total length of the national road segment is 2632.22 Km, an increase of 328.56 km from the previous road length. By increasing the power factor of the existing national street lighting and utilizing lamps with high efficacy and utilization of solar cells on the increase of national roads will be obtained energy conservation and the need for electrical power for the purposes of street lighting by increasing the road segment becomes fulfilled.
