We develop a control system to reduce peak power demand by using the internal batteries of office notebook PCs. This system plans a recharging schedule that takes into consideration a demand forecast and user usage, it can handle a wide range of power demand fluctuation without loss of usability. In this paper, we present a synopsis of the system and a local search algorithm to solve the optimal control problem to plan an optimal recharging schedule.

In this paper, a home electric supply system consisting of a fuel cell (FC) and electric double layer capacitor (EDLC) is proposed. Steady load is supplied by FC and transient power component will be compensated by EDLC. The response characteristics of this system is confirmed with simulation by software PSlM. The modified Euler type Moving Average Prediction (EMAP) model is introduced to reduce the required capacity of EDLC, with the simulation by software MATLAB/Simulink.
