Abstract

Demand response is a method to increase efficiency of power grid which should be utilized in the next generation of power grid. In this paper, we propose a generalized model of users´ electrical power consumption and a distributed demand management scheme in which we could achieve the maximization of total users´ utility in power grid. Considering the limited communication situation in power grid, we present an event-triggered demand response scheme to reduce the message transmission between energy provider and energy consumption side. The efficiency of the proposed scheme is verified via simulations.
