Demand side load management for residential buildings

Abstract

Demand-side load management is essential for controlling loads inside the residential buildings to satisfy the user requirement at low cost. This paper presents a Fuzzy inference model to be evaluated with four linguistic variables namely the power consumption of the appliances, its time of utilization, electrical power utilization in kWh and also the user satisfaction on each electrical appliances at each hour of the day. From the user data, the system can provide an energy utilization design, which in turn gives maximum satisfaction at a predefined user budget to the user. In this work the function of cost is based on the user expenditure and the cost function is predefined as Rs3/day. Randomly selected appliances can be utilized by the user based on the predefined cost. Result of the work provides maximum user satisfaction and minimum cost at the value of predefined cost function.
