Smart Operation of Centralized Temperature Control System in Multi-Unit Residential Buildings

摘要

This paper presents the mathematical modelling of a Centralized Temperature Control System (CTCS) of a Multi-Unit Residential Building (MURB) and its optimal operation considering electricity prices and weather variations. The model considers comfort levels, preference settings and activity level of residents in different units of the building to determine the optimal operation schedules of the CTCS, minimizing its total energy consumption cost considering multi-objective operation when residents in different units have conflicting interests. The proposed model is a Mixed Integer Non Linear Programing (MINLP) model, where some of the constraints are linearized to reduce computational complexity for real-time applications. The model is studied for various customers preferences using a realistic MURB model. Simulation results show that significant cost savings can be achieved using the proposed model.
