Abstract

In order to strengthen energy security while reducing environmental impact, particularly from global warming and greenhouse gas (GHG) emissions, the government of Thailand has established a 20-year Energy Efficiency Development Plan (EEDP), aiming to reduce a 20% share of final energy consumption by 2030. The energy saving potential assessment reveals that the forecasted energy saving by the residential sector holds more than 60% of the overall electricity saving shares. Therefore, in this paper, the situation of Thailand's energy is presented and the energy conservation plan is reviewed. Next, a smart demand responsive energy management system under ZigBee/IEEE 802.15.4 based wireless communication is proposed. An analysis of demand response potential in terms of a time-of-use (TOU) pricing without enabling technology program in Thailand scenario is also investigated. Finally, by using the proposed load characterization and load prioritization under the concept of a smart energy management system, the bill savings benefits of a demand responsive program can be proved while the target of energy saving is also achieved.
