Aplicación de los sistemas de almacenamiento de energía en las redes eléctricas para el abastecimiento de la demanda usando flujos óptimos de potencia AC

Abstract

The research has developed a mathematical optimization model that determines the hourly power to be dispatched by generators, taking into account technologies such as: hydroelectric, wind, photovoltaic and thermal; and, also assigning the hourly participation of electrical energy storage systems in the supply of demand, modeling a test system for which load or AC power flows are used. The mathematical model is applied to an IEEE 24 node model system, obtaining as results the minimization of costs in the supply of demand, the dispatch of active and reactive power of each generator during the 24-hour period, the power flows through the links and the contribution of the storage system in the coverage of the hourly load, focusing the analysis mainly on the minimum, average and maximum demand. The modeling highlights the modeling of battery-based storage systems, which, by interacting in the electrical system depending on the use of intermittent energies, network restrictions based on AC power flows and market prices, demand obtains important benefits which are analyzed from a technical and economic point of view.
