Despite the fact that the term improved/new product development is not new, very few studies have investigated the effect of improved electricity product development on the business performance of a public electricity transmission company, most especially in a developing country such as Nigeria. This paper present means by which improved electricity product development can be used to assist electricity transmission company's business performance in order to improve customers' electricity product adoption and other stakeholder's satisfaction in the industry. It is based on a case study of the Transmission Company of Nigeria (TCN), it provide guidelines to stakeholders in the industry in utilizing improved electricity product development to better support electricity transmission companies: it allows transmission companies to launch improved electricity products to end-users; it helps transmission companies to determine the weaknesses of the electricity product delivered to end-users; it allows improved quality of electricity product that customers are willing to pay a premium for, while eliminating epileptic electric-power supply end-users do not want.","PeriodicalId":6601,"journal":{"name":"2017 IEEE PES PowerAfrica","volume":"88 1","pages":"46-51"},"PeriodicalIF":0.0,"publicationDate":"2017-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85833739","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}

The non-availability of metering data when needed or the untimely delivery of data needed for control operations will undermine the activities of these back-end systems. Unfortunately, there are concerns that cyber attacks such as distributed denial of service (DDoS) will manifest in magnitude and complexity in a smart grid AMI network. Such attacks will range from a delay in the availability of end user's metering data to complete denial in the case of a grounded network. This paper proposes a cloud-based (IaaS) firewall for the mitigation of DDoS attacks in a smart grid AMI network. The proposed firewall has the ability of not only mitigating the effects of DDoS attack but can prevent the attack before they are launched. Our proposed firewall system leverages on cloud computing technology which has an added advantage of reducing the burden of data computations and storage for smart grid AMI back-end systems. The openflow firewall proposed in this study is a better security solution with regards to the traditional on-premises DoS solutions which cannot cope with the wide range of new attacks targeting the smart grid AMI network infrastructure. Simulation results generated from the study show that our model can guarantee the availability of metering/control data and could be used to improve the QoS of the smart grid AMI network under a DDoS attack scenario.","PeriodicalId":6601,"journal":{"name":"2017 IEEE PES PowerAfrica","volume":"28 1","pages":"28-33"},"PeriodicalIF":0.0,"publicationDate":"2017-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83639174","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}

Nearly 600 million people in Africa lack access to electricity which majority of them residing in the sub-Saharan African (SSA) countries. Electricity consumption in SSA countries excluding South Africa is 153kwh/year. The current installed capacity is at 147 GW which is equivalent to China's install capacity for one or two years. The road to electrification in SSA countries is either through grid extension, high penetration of off-grid technologies such as standalone systems and microgrids. Given the abundant natural and vast geographical advantage, the potential for renewable energy sources is vast in SSA countries. This paper aims to present detailed review on the ongoing renewable energy supported technology for rural electrification of sub-Saharan Africa region. It will discuss issue of energy poverty and why that is directly related to the lagging economy of these countries. It will detail some of the off-grid and microgrid developments. Challenges facing this development will be discussed. Finally, it will conclude by reflecting on the impact of the future off-grid renewable technologies, the status and challenges of rural electrification.","PeriodicalId":6601,"journal":{"name":"2017 IEEE PES PowerAfrica","volume":"55 1","pages":"595-599"},"PeriodicalIF":0.0,"publicationDate":"2017-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79736905","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}
