In this paper, the smart demand responsive energy
management system under ZigBee based wireless
communication is proposed. The opportunities and challenges
for Thai residential sector are discussed. The analysis of
demand response potential in term of time-of-use (TOU)
pricing without enabling technology program in Thailand
scenario is also investigated particular in residential group. By
applying the proposed load characterization and load
prioritization under the concept of energy management system,
the bill savings benefits of demand response program can be
proved. Results from this study could also help in term of
energy management and planning in the future. It is also
helpful for PEA to provide optimum electricity for household.
Furthermore, both energy efficiency and demand response
principles should be included and coordinated in education
programs and action plans, to broaden household consumer
understanding, improve results and use demand-responsive
program resources effectively.
