This work proposed the switching control strategy for household appliances in a rural area that based their storage on the battery for three days. The system is to track the state of charge (SOC) of the battery to balance with the demand from the output appliances. The existing controller or regulator tries to off all the appliances when the SOC is reaching a certain level. However, to avoid a total blackout and to avoid at least an appliance to be working. Thus, we try to design an intelligent discrete-time controller and optimize the controller parameter for the set point control followed the base rule. The system performance result shows that proposed switch control strategies work within a certain limit and avoid total discharge of the battery.
