Abstract—In order to enable the demand responsive program
which is in the extension of the smart grid, a smart and wireless
home energy management application plays a key important role.
Therefore, in this paper, first the smart demand responsive
energy management system under ZigBee/IEEE 802.15.4 based
wireless communication is proposed. As the focus of this
paper, the hardware design and implementation of a
multiple nodes ZigBee based wireless sensor network are
discussed. The communication protocol and software design for
both wireless sensor network node and base station based on the
CC2430 system on chip are also presented in detail. The analysis
of demand response potential in term of 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
smart home energy management system, the bill savings benefits
of demand responsive program can be proved while the target of
energy saving is also achieved.
