Investigation of Nigerian 330 Kv Electrical Network with Distributed Generation Penetration − Part I: Basic Analyses.

Abstract

The first part o f this paper presents the basic analyses carried out on Nigerian 330 kV electrical network with distributed generation (DG) penetration. The analyses include load flow, short circuit, transient stability, modal/eigenvalues calculation and harmonics. The proposed network is an expanded network of the present network incorporating wind, solar and small-hydro sources. The choice of some locations of distributed generation has been proposed by energy commission of Nigeria (ECN). The conventional sources and distributed generation were modeled using a calculation program called PowerFactory, written by DIgSILENT.
