Applying demand side management using a generalised three phase grid supportive approach

Abstract

Demand side management is often seen as a promising tool for distribution network operators to mitigate network operation limit violations. Many demand side management applications have been proposed, each with their own objectives and methodology. Quite often, these demand side management applications do not have a direct interface with the network monitoring applications of the network operator, and therefore are not always capable of resolving operation limit violations effectively. Besides, for network operators it can be difficult to deal with the various types of demand side management applications run by different aggregators or energy suppliers. Therefore, this paper proposes a generalised three phase grid supportive demand side management approach for distribution networks, establishing a new interface between the monitoring and network analysis tools of the network operator and the demand side management application. Using the network sensitivity, independently of what objective de demand side management application pursues, the demand side management application will be able to resolve network operation limit violations as specified by the network operator. A case study based on fair power sharing shows the applicability of the proposed approach for mitigating over and under voltages as well as over currents simultaneously, followed by recommendations for future work and conclusions.
