“…Previous work on the feasibility study reported [1] the results of planning considerations and it focuses on the analysis of loadflows, short circuit evaluation and transient stability studies when various sizes of CSP plant are considered at Upington substation. In this paper, focus is placed on evaluating the impacts on voltage dip impact when these plants are integrated, and, therefore the impact on the quality of supply of the network.…”

The Upington area within South Africa is wellendowed with solar resources, with relatively high annual solar radiation recorded compared to other parts of the country. The distribution network in the area comprises very long lines, has very low fault levels, and is very prone to voltage dips. Previous studies [ 1 ] have investigated the feasibility and network considerations of connecting concentrating solar power (CSP) plants of sizes 50 MW, 100 MW and 150 MW at Upington substation. In this paper, the previous work is extended to assess the impact of connecting the plant sizes described above on the voltage dip performance of this weak network. The studies show that embedding a CSP plant in such a weak network, apart from capacity-related benefits, can have positive on quality of supply of such a system by reducing the severity of dips due to disturbances.
