Impacts of direct load control on reinforcement costs in distribution networks

Based on the GreenLys Smart Grid experiment taking place in the cities of Grenoble and Lyon (France), this paper presents a quantitative method to evaluate the benefits of load control for the reinforcement costs of distribution networks. Preliminary results of this experimentation have led authors to develop a linear model that estimates the modification of electric demand caused by direct load control. The impact of demand control on the distribution network reinforcement costs is further discussed. The developed approach highlights the reinforcement costs savings potential of direct load control for urban areas.
