Despacho óptimo de corto plazo del sistema híbrido de las islas Santa Cruz y Baltra considerando el manejo de las variables estocástica

Abstract

In the present work, develops a methodology in the surroundings DPL of the software DIgSILENT Power Factory, to determine the economic dispatch of short term (24 hours) of the Hybrid System of the Islands Santa Cruz and Baltra that consists of thermal, wind and Solar photovoltaic generation. To determine the power forecast provided by the renewable generation sources, a historical data treatment (wind speed and solar radiation) is performed by using the Montecarlo Simulation Techniques associated with the normal and weibull probability functions. The predicted power values obtained for the 24 hours of a typical day are introduced into the optimal power flow with the objective of minimizing thermal generation costs, these renewable sources behaving as static where at each instant of time they deliver all the determined forecast and As it is not enough to supply the demand of the system it is complemented with thermal generation using the interior point method.
