Demand side management strategy for alleviating power shortages in Nigerian power system: A case study

Abstract

This paper presents the simulation of demand side management (DSM) strategy for alleviating power shortages in Nigerian power system. The frequent power outages in the Nigerian power system especially in the distribution network which is caused by schedule and unscheduled outages in the system in which the schedule outages are predominant, is as a result of inadequate electricity generation and equipment limitations to meet the current ever-growing energy demand. The distribution network feeders’ peak load and electricity supply was evaluated and data were collected from November 2017 to October 2018; to carry out the analysis of the network feeders’ load and its management. Consequently, modeling of the proposed DSM strategy in Simulink environment and its optimization was done using the binary particle swarm optimization (BPSO) algorithm and, the simulations were carried out to test the efficacy of the model. The results of the simulations of the DSM strategy showed that the proposed method has the capacity to bring the load curve closer to an objective or desired load curve thereby reducing the blackout areas of the network per outage scheduling from 63.38% or 36.62% in the existing network to 14.08% in the proposed network and also, improved the 11 kV feeders’ availability from twelve hours currently per day to twenty-four hours in the proposed network.

The economic viability of commercial-scale hydroponics: Nigeria as a case study

“…On the other hand, medium-scale farms were situated around the city outskirts and mainly used nutrient film techniques (NFT) and deep-water culture (DWC) systems. The small-scale farmers relied primarily on the national electricity grid, which is mainly unstable [ 23 ]. In contrast, medium-scale farmers carried out their operations using power generators, while the national grid's electricity was used sparingly.…”

“…The simulation results showed a reduction in the network blackout areas per scheduled outage from 36.62% in the existing network to 14.08% in the proposed network. Additionally, the load curve was maintained nearer to the desired one [36].…”

Transient Stability Improvement on Power Network using Static Synchronous Compensator: A Case of The Nigerian 330 KV Electricity Grid

“…Therefore, the goal of this study was to employ STATCOM for power system transient stability improvement considering the Nigerian 330 kV electricity grid. The Nigerian electricity grid which comprises complex interconnections of varieties of essential equipment is currently overstressed due to excessive electrical energy demand warranted by the persistently increasing population and industrialization (Adebisi et al, 2018;Akpojedje & Ogujor, 2021;Igwilo et al, 2021). Occurrence of transient disturbances such as faults, rapid load changes, switching operations and loss of components on the system already operating near its stability limit is inevitable and this usually lead to severe loss of synchronism on the generators with the end result being voltage collapse in the entire network.…”
