Abstract

One way to improve the efficiency of the electricity system is by including demand participation in the market, as opposed to the traditional supply-follow-demand approach. In this work, we build upon literature to model a general T-period electricity market consisting of price-taking prosumers with multiple types of appliances, an utility company and a social planner distribution system operator (DSO), where we remove the restricting assumptions that prosumer cannot be net-sellers and EVs cannot discharge back to the grid. We show that a social welfare maximizing market equilibrium exists. Furthermore, through a case study with quadratic utility functions, we characterize explicitly the social welfare improvement, resulting from allowing prosumers to be a net-seller and EVs to discharge, as a function of utility function parameters by using quadratic programming duality.
