ABSTRACT: Electricity network is a very complex entity that comprises several
components like generators, transmission lines, loads among others. As
technologies continue to evolve, the complexity of the electricity network has
also increased as more devices are being connected to the network. To
understand the physical laws governing the operation of the network, techniques
such as optimal power flow (OPF), Economic dispatch (ED) and Security
constrained optimal power flow (SCOPF) were developed. These techniques have
been used extensively in network operation, planning and so on. However, an
in-depth presentation showcasing the merits and demerits of these techniques is
still lacking in the literature. Hence, this paper intends to fill this gap. In
this paper, Economic dispatch, optimal power flow and security-constrained
optimal power flow are applied to a 3-bus test system using a linear
programming approach. The results of the ED, OPF and SC-OPF are compared and
presented.
