“…Many African countries will be making huge investments in the power sector in the coming years to expand energy access while promoting environmental sustainability ( Ayamolowo et al., 2022 ; Du et al., 2021 ; Maji et al., 2019 ; Mutombo and Numbi, 2019 ; Qudrat-Ullah and Nevo, 2021 ). Also, vehicle ownership is expected to rise exponentially in the continent owing to the projected population growth rate, urbanization, and the general desire for private car ownership.…”

“…Mukoro et al's (2021) work predict that by 2040, renewable energy capacity in Africa is expected to reach 169.4 GW from 48.5 GW in 2019. Specifically, in South Africa, as of 2021, a total of 6,422 MW of power has been acquired across 112 renewable energy Independent Power Producers (Ayamolowo et al, 2022). The inevitability of more frequent and more extensive floods, displaying the inherent variability of climate, continued to be studied under the blue cluster (Ficchi et al, 2021;Petrova, 2022).…”

An overview of climate change adaptation and mitigation research in Africa

Research on climate change has increased significantly since the 1970s. There has also been a particular focus on Africa, given its vulnerability to climate change impacts and its urbanization trends that may have massive implications for climate change adaptation and mitigation. Despite the wealth of publications on climate change in Africa, there is a lack of review studies that highlight the overall research landscape. If this status of climate research is clarified, African countries can better deal with climate change. Hence, this paper aims to improve our understanding of the status and trends of research on climate change adaptation and mitigation in Africa. Our review, straddling from 1990 to late 2021, recognizes the foundations that underpin climate change adaptation and mitigation literature. Based on keywords associated with Africa's climate change adaptation and mitigation, we undertook bibliometric research by collecting 3,316 related SCI/SSCI articles. In addition, we provided a thematic evolution over three decades, compartmentalized into four sub-periods (1990–2007; 2008–2014; 2015–2019; 2020–2021). Priority research topics and themes have been dynamic over time, with some core concepts receiving more attention (vulnerability, food, water, and energy security). Although the number of published articles exhibited a rapidly growing trend, their distribution is extremely uneven. Articles were mainly published by institutions from certain parts of the continent, with the University of Cape Town, making the highest contribution. About 72% of the existing studies focused on climate change adaptation, while climate change mitigation was less represented with 22%. The results also showed that researchers have examined not all African countries. South Africa, Ethiopia, and Ghana are hot spots, while most countries are largely neglected. Africa and African countries need to improve their future research ability on climate change mitigation. Assessing climate change risks and measures in African countries should be prioritized.

“…This paper focuses on the grid integration of RE in South Africa, which has recently experienced several challenges surrounding supply reliability of the country's energy needs, leading to a decline in the average Energy Availability Factor (EAF) down to only 65% in 2020 (Hanto et al, 2022). This follows years of infrastructure neglect and lack of maintenance leading Eskom, the country's primary energy provider, to battle unplanned breakdowns of its old and poorly maintained power plants to remain below 9,500 MW, at which point planned load shedding is initiated to maintain stability of the country's strained electrical grid (Statistics South Africa, 2018Eskom, 2019bEskom, , 2019aEskom generation division, 2019;Maune, 2019;Creamer, 2021;Ayamolowo et al, 2022). As part of the solution to the ongoing energy crises South Africa is planning to significantly ramp up its use of RE for electricity production, and therefore developed RE specific grid codes to potentially limit added instabilities brought about by its integration.…”

Purpose Despite South Africa’s ailing electrical grid, substantial renewable energy (RE) integration is planned for the country. As grid-integrated RE affects all grids differently, this study aims to develop an adaptable grid code-guided renewable power plant (RPP) control real-time simulation testbed, tailored to South African grid code requirements to study grid-integrated RE’s behaviour concerning South Africa’s unique conditions. Design/methodology/approach The testbed is designed using MATLAB’s Simulink and live script environments, to create an adaptable model where grid, RPP and RPP guiding grid codes are tailorable. This model is integrated with OPAL-RT’s RT-LAB and brought to real-time simulation using OPAL-RT’s OP4510 simulator. Voltage, frequency and short-circuit event case studies are performed through which the testbed’s abilities and performance are assessed. Findings Case study results show the following. The testbed accurately represents grid code voltage and frequency requirements. RPP point of connection (POC) conditions are consistently recognized and tracked, according to which the testbed then operates simulated RPPs, validating its design. Short-circuit event simulations show the simulated wind farm supports POC conditions relative to short-circuit intensity by curtailing active power in favour of reactive power, in line with local grid code requirements. Originality/value To the best of the authors’ knowledge, this is the first design of an adaptable grid code-guided RPP control testbed, tailored to South African grid code requirements in line with which RPP behavioural and grid integration studies can be performed.
