Abstract—We are proposing a load shedding system for future smart cities which can shed load on priority basis. The proposed methodology has the potential to conserve the available energy in an efficient manner and making system immune to intense blackouts and brownouts. The objective is to keep end-user with more reliable and increased power availability and hence keeping higher priority load connected. Load is categorized in flexible manner to provide freedom of priority demarcation. The proposed system consists of two basic controllers: Central Load Manager (CLM) and Local Load Manager (LLM). CLM through sensor receives the real time load demand data, check for its value against threshold power and takes decision accordingly. Control signals are then transmitted to local load manager using TCP/IP technology which acts to shed the load and keeps condition of load (data) in the memory. An extensive simulation environment is developed in SIMULINK-MATLAB and tested under diverse conditions to analyze system’s performance and practicality.
