The increasing complexity of the conventional grid due to population growth,advancement in technology and infrastructure,all of which contribute immensely to in stability,insecurity,poor power quality and insufficient energy sustainability,calls for the use of renewable energy as a sustainable power supply [28]. The development of distributed generation has increased since the
privatization of Independent Power Producers(IPPs) and is currently being further encouraged by the governments'new energy policy.The primary aim is to supply energy that is environmentally friendly,which supports a relatively low carbon economy. Renewable energy(RE) has been generally accepted globally as a
