Abstract
The first part of 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 Po-werFactory, written by digsilent. Short-circuit analysis is used in determining the expected maximum currents, while transients stability and modal analyses are considered during the planning, design and in determining the best economical operation for the proposed network. One common application of harmonic analysis is providing solution to series resonance problems. Also, they are very valuable for setting the proper protection devices to ensure the security of the system.
