Abstract

With the world in pursuit of increased sources of clean energy, it is equally important to reduce our excessive energy consumption and thereby adjusting to the power generation. Demand Response (DR) has gained even more significance with the advent of Smart Grids. Today, it is perceived as the most cost effective solution for ensuring adequate energy supply. A detailed study and approach is essential before we integrate large volume of DR into the current electrical grid. This work illustrates a potential problem while employing DR in distribution grid operations. After the careful consideration of Voltage-reactive power Control (VVC), load modeling and DR, the concept of Demand Response Inefficiency (DRI) is introduced which indicates the inefficiency occurred during the implementation of DR in a distribution system. A comprehensive study is conducted which shows the relationship of DRI with respect to the power factor, load reduction amounts, load models and the DR location. A standard UK Generic Distribution System is utilized for the analysis. To tackle the problem of DRI, a Mixed Integer Non Linear Programming (MINLP) Model is formulated which uses the transformer tap changers and Static Synchronous Compensators (STATCOMs) as the solution components by the coordination of VVC with DR. Solution is obtained for various cases and the different solution schemes are compared for their effectiveness.
