Separation of the two processes of network expansion whose results must be combined during implementation will often lead to sub-optimal expansion plans. This concern has given rise to the integrated Generation and Transmission Expansion Planning (GTEP) optimization problem. In this paper the GTEP problem is formulated in a multi-objective and dynamic environment. The multi-objective function considers investment, production and outage costs as well as penalties related to system voltage violations and active power loss. In addition, the proposed formulation considers system redundancy. To increase on the reliability of the results the formulations are based on AC power flow models. The formulated MOGTEP problem is optimized using adaptive hybrid meta-heuristic approach. This approach is suitable for handling the highly dimensional and complex problem. The obtained results showed the superiority of the proposed MODGTEP formulation and solution methodology to other reviewed solution techniques. The proposed methodology produced less costly and more reliable expansion plans. Inclusion of the contingency analysis led to increase in the committed elements (generators and transmission lines) so as to account for any planned and forced outages in the system.","PeriodicalId":325937,"journal":{"name":"2020 IEEE PES/IAS PowerAfrica","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133883896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A COVID-19 pandemic that has spread rapidly in many different regions and countries, such as South Africa, affects health systems, economies, and societies. The South African electricity sector was also affected by the pandemic, experiencing shocks in supply and demand, putting further pressure on the country's energy systems. In this context, this study explored the preliminary impacts caused by the COVID-19 pandemic in the South African electricity sector. Such consequences resulting from the containment measures and changes in the behavior of electricity use were investigated during the seven weeks after the beginning of the country's lockdown. To achieve the aim of this paper, exploratory research was carried out, given that the phenomenon is at an early stage, making use of three secondary research methods. The results show the severe drops in electricity consumption and peak demand, which reached 28.1% and 20.2%, respectively. Finally, it is presented the challenges faced by the South African electricity sector in the context of the pandemic, highlighting the possible ways to be traced to overcome these barriers in the post-pandemic, focusing on policy structures of the country's electricity sector.","PeriodicalId":325937,"journal":{"name":"2020 IEEE PES/IAS PowerAfrica","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133251107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
