Study by Microgrids of the Current and Future Demand of the Coverage Area of Substation 57 Pomasqui of the Metropolitan District of Quito

Abstract

This work analyzes the current demand for the coverage area of Substation 57 Pomasqui owned by the Empresa Electrica Quito (EEQ) and it establishes the forecasted demand at 2018 by using a technique for microgrids. To do this, the study considers two major stages: 1) determination of the maximum demand at each microgrid, and 2) estimation of the land use based on the Plan de Uso y Ocupacion del Suelo (PUOS) promulgated by Plan Metropolitano de Ordenamiento Territorial (PMOT) of the city of Quito. The results obtained in these two stages are used, in conjunction with the logistic curve, to make the forecasting of the demand at 2018. That is, it is based on the fact that the growth of the electric demand follows the behavior of the logistic curve and it considers the results of the forecast of the demand. This establishes a procedure that allows to estimate the demand for the year 2018. Finally, with the results of the forecasted demand for 2018, power flow studies are performed using the CYMDIST software to estimate the future operating conditions. This helps detecting possible problems and discussing alternative solutions in the short and medium term distribution planning.
