Analysis of Effectiveness of Flexible Load Shifting Order on Optimum DSM

The problem of demand and supply balance is usually addressed at the generation side by addition of capacity to meet the load demand. With the recent trend in energy market, the problem of peak load demand can also be met from the user end. Hence, demand side management came into practice and it is one of the important aspect of microgrid through which the consumers can take an informed decision regarding their electricity consumption and benefits the energy providers in minimizing the peak demand by modifying the load profile. Load management is one of the most important components of demand side management to regulate the consumption of electricity. The energy management techniques presented in this paper is based on order of shifting of flexible loads. The flexible loads are shifted to obtain a flat load demand which in turn reduces the peak demand. Three different procedures are used for selecting which load to shift first and the methods are compared to decide most suitable one. The proposed method is supported with a case study of residential loads. This technique of load management improves the system reliability and makes the system sustainable.
