Price and output control in a community power network with renewable generations

Abstract

With the increasing popularity of the renewable generation sources these days, we are facing the great challenges on how to integrate them into a community distribution network smoothly. The variability of renewable generation makes it difficult to maintain the voltage stability. As a widely accepted solution that requires the least change on the substation controllers, the output of a renewable generator needs to be controlled so that no power is injected from a distribution network substation into a transmission network. In this paper, we design a control policy that regulates the power output from the renewable generators. We further leverage the price control to discourage non-collaborative behaviors so that this policy can not only guarantee the stability of the distribution network, but also ensure the fairness of generators in case of non-collaborations. Through simulations we demonstrate that this policy enables us to integrate renewable generations to achieve their benefits while limiting their disadvantages.
