Integration of DGs in utility networks has increased significantly over the past years primarily as a result of growing energy demand, coupled with the environmental impacts posed by conventional fossil fuel-based generation. Improper planning of grid integration of intermittent DGs such as wind and solar PV may however pose negative impacts on the quality of power supplied by utility networks. This...
Grid integration of renewable DGs has significantly increased over the past years as a result of growing energy demand and an attempt to reduce the greenhouse gas emissions from fossil fuel-based power generation. Integration of intermittent DGs may however pose negative impacts on the quality of power supplied by the utility grid. This paper explores the possibility of improving network's PQ using...
Power system restoration continues to be a major challenge for many power systems in sub-Saharan Africa. Hydropower generation also remains as one of the major sources of power in this region. However, many power systems supported by hydropower generation in this region suffer from frequent power system blackouts, which have detrimental implications on the power system and its users. This paper focuses...
Electrification of rural households is of key importance for Africa's economic growth, particularly for developing countries such as Botswana. This paper carries out a techno-economic feasibility study of a solar biomass hybrid system with and without energy storage to supply load demand. The case studies were performed using HOMER software, choosing Phakalane, a village of Botswana as a location...
This paper presents a comprehensive review on various impacts of DG integration on PQ and importance of proper grid-integration planning in light of maintaining PQ at the levels compliant with grid code requirements. It also focusses on the effective utilization of DGs for power quality enhancement in the utility grids. The proposed solutions essential for PQ enhancement in electricity networks with...
Wind energy conversion systems (WECSs) are currently the most matured and preferred as bulk renewable energy generation systems across the world. Hence extensive research is being done on investigating the impact of wind energy integration on voltage and frequency of electricity networks for proper planning of their grid-integration such that network performance is not deteriorated, rather enhanced...
