An Efficient Scheduling of Electrical Appliance in Micro Grid Based on Heuristic Techniques

Enabling electricity access: revisiting load models for AC‐grid operation ‐ Part I

“…The topic of peak to average ratio reduction through appliance scheduling was investigated in literature through various approaches [29][30][31][32]. The topic was discussed in [29] through a human expert based methodology.…”

“…By reviewing the work in [31], it was visible that it was limited to shiftable and non shiftable appliances where each appliance has a specific watt consumption rather than an operational load model (a function of electricity availability, temperature…etc) as will be presented in this paper. The scheduling problem in [31] was handled through heuristic techniques without incorporating AC power flow to verify the scheduled pattern as with the grid operational codes. The latter was also not accounted for in [33].…”

“…In [30], a multi‐objective function of a mixed integer linear programming (MILP) problem was applied for peak load and electricity cost reductions in a goal programming approach. A similar appliance scheduling problem was presented in [31] where the minimised objective consisted of two parts: electricity cost and peak‐to‐average ratio. Also, the peak‐to‐average ratio and energy consumption minimisations were both achieved in [32] in an environment enabling pricing at the end of the day.…”
