Asignación de precios dinámicos en tiempo real para micro-redes con recursos energéticos renovables distribuidos basado en la desviación de la demanda.

Abstract

In this paper shows a detailed analysis of the management in a microgrid that has different types of generation, such as wind, photovoltaic solar, CHP cogeneration systems and demand response programs (PRD) that allow to supply the load in the form efficient, the analysis considering of each resources, especially those variables of high uncertainty such as load, wind speed, irradiance and prices, in order to obtain results that are closer to the reality of an electrical system, performing the discretization of the probability density function (PDF) in each uncertain parameter. Using a heuristic based on the two-stage stochastic optimization approach and optimal power flows based of mixed integer linear programming, it is intended to analyze the behavior of the microgrid in real time, in such a way as to allow constant monitoring of the load variation and supply this load in a timely manner, as well as the allocation of dynamic prices that allow the implementation of optimal demand response programs. Three studies cases are proposed, the first connected to the network, the second connected to the network with PDR and the third in island mode.
