An alternative approach to solar and grid-connected hybrid electricity for homes and buildings in Malaysia

Abstract

This paper presents the proposal of a solar and grid-connected hybrid electricity system for homes and also buildings. A new concept of using a DC motor and synchronous generator as an electromechanical inverter is proposed as an alternative system to presently popular approach of using solid-state inverters to convert the solar DC supply into AC, suitable to run common electrical appliances. A 2kW hybrid system is proposed with the block concept of the system, solar panels quantity and synchronizing control. A simulation was done for the system using PSIM and the results are shown as the system was subjected to some voltage and phase variations.
