A demand side management approach to increase self-consumption in buildings

Abstract There is a growing interest in increasing the presence of renewable energy electric network. Photovoltaic production from grid-connected systems leading this growth terms households. Alongside development, concern about network security has emerged, because excesses intermittent on grid could exceed voltage limits. Self-consumption, understood as capacity producer to consume his or her own production, can partially solve these problems. Thermostatic controllable loads, such heating and cooling, represent 50% total amount consumed by buildings; proper allocation loads be driving force for self-consumption. In study, demand side management strategy proposed based building model equipped with an inverter heat pump coupled photovoltaic plant. The goal maximize use local plant (self-consumption), reducing export import grid. This achieved optimizing set-points each room. An array optimal over six years presented. results show methodology match similar values self-consumption (70% winter summer) obtained strategies chemical batteries. findings are shown matching chart at different levels detail (yearly monthly). Color bubbles added help visualize unmatched system graphically. comparison actual predictive control technologies, study’s offers great simplicity large saving computational time.
