With the increase in population, electricity demand is also raised. The development of distribution systems (DSs), the optimal utilisation of shunt capacitor banks (SCBs) and distributed generators (DGs) in the DSs are heightened. In this paper, a methodology is proposed to allocate both DGs and SCBs simultaneously on the DS. The objectives are to minimise power loss, improving the voltage profile and voltage stability index (VSI) of the DS. First locations of DGs and SCBs are found out by loss sensitivity factor (LSF) technique. Next grasshopper optimisation algorithm (GOA) is used to determine the rating of these sources. The methodology is implemented on IEEE 33 and 69 bus test systems considering optimal allocation of multiple DGs without and with placement of capacitors. Finally, the results obtained by the proposed method are compared with GA/PSO and PSO methods.","PeriodicalId":35754,"journal":{"name":"International Journal of Energy Technology and Policy","volume":"16 1","pages":"563"},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47541478","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}

Due to associated complexities and uncertainties, decision makers and energy planners face increasing pressure to effectively address energy related challenges, including approaches to low carbon energy provision. This study seeks to develop a long-term, 2010-2050, system dynamics (SD) model of the Nigerian power sector (NPS). The model then helps to investigate ways to bridge the electricity supply and demand gaps by simulating various performance scenarios based on real socio-economic variables and estimation of CO2. A total of six policy scenarios were implemented. These scenarios sought to evaluate the influence of the following four parameters: 1) transmission losses (Tx); 2) time to adjust capacity (TAC); 3) population growth rate (PGR); 4) capacities under construction. Accordingly, results not only showed that the completion of the existing project and the Mambilla multipurpose hydropower (MMHP) would make the NPS 71% energy secured, but also revealed a paradigm shift in CO2 reduction in the planning process considered by the study in contrast to the existing generations. Finally, capability of SD was affirmed by properly capturing feedbacks, delays, and other complexities in the NPS.","PeriodicalId":35754,"journal":{"name":"International Journal of Energy Technology and Policy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47492226","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}

In this paper, by using wind power in distribution system and basic forward backward sweep load flow method is used for analysing the affect of harmonics on nodal prices. The method uses marginal loss coefficients (MLCs) to get these prices, the results are compared with realistic ZIP and normal or constant power (CP) loads.

According to the results, in 2025, the capacity of Iran's petrochemical productions will range from 73 to 78 million tons. Also, the value of products will range from 26 to 36 million dollars (USD) in 2025 that can be an interesting research area to investigate how the value of diversified petrochemical products can be increased.

The devices such as tractors, power tillers using diesel and irrigation pump-sets using electricity, which consumes major portion of the energy inputs are assumed to be the representative of Indian agricultural sector. It is found that during the study period the overall exergy efficiencies (66.05% to 68.46%) are slightly less than corresponding energy efficiencies (66.09% to 68.47%). The energy and exergy flow diagrams and further improvement potential of this important sector are also presented.

However, driven by fiscal priorities, state programs are increasingly resorting to aggressive tariff reduction to minimise compliance costs. This article first highlights the trends in solar tariffs and estimates the underlying levelised cost of energy (LCOE). We further delve into the broader institutional context and sectoral issues that motivate these trends. Finally, we evaluate the implications of low tariffs from the perspective of risk using quantitative simulations. Our results suggest that the levelised costs vary widely when evaluated against different risk scenarios. Based on these results we propose recommendations for policy makers in the context of determining tariffs that balance the interests of different stakeholders.","PeriodicalId":35754,"journal":{"name":"International Journal of Energy Technology and Policy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44954114","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}

In the proposed model, the responses of consumers to selling prices offered by the retailer are integrated with three types of electricity transactions. In our model, we deal with the three types of electricity transactions, i.e., forward contracts, day-ahead market transactions, and real-time market transactions, and consumers optimise the electricity consumption schedules in response to the time-of-use (TOU) selling prices offered by the retailer. In this paper, in order to examine behavior of the retailers with various risk attitudes effectively, we employ the fractile model that can find the preferred solution in the proposed non-convex decision-making model. Through the computational experiments, we demonstrate the validity of the proposed model for examining the retailer's actions in the deregulated electricity market.","PeriodicalId":35754,"journal":{"name":"International Journal of Energy Technology and Policy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47239045","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}
