This paper aims to improve the understanding of the opportunities and constraints of decarbonizing India’s electricity sector and adds to the growing body of literature by modelling the electricity sector in India with a dynamic optimization approach that assesses options for effective greenhouse reductions through carbon pricing. Attaining significant variable renewable energy penetration in India by 2050 is consistent with the lowest cost power generation options identified through our simulations, where solar and wind can provide 66 % of the electricity needs by 2050, even without a carbon price. With a carbon price of US$50/tCO2e, the simulations project that wind and power generation share in the electricity mix will rise to 81 %, leading to significant emission reductions. In this scenario, power sector emissions will be 164 million tCO2e by 2050, which is only about 14 % of the emissions levels in 2019. The analysis also indicates that fossil fuels remain part of India’s electricity mix in 2050, but their role and operation would dramatically change. When a carbon price of US$50/tCO2e is introduced, coal capacity remains valuable to fill demand when solar and wind are not available. This would require modifications in operation schedules and repurposing coal power plants for frequent ramping up and down.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"36 6","pages":"Article 107291"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50177200","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}

To answer this question, we analyzed data from the Pennsylvania-New Jersey-Maryland (PJM) market (with relatively low, approximately 3% wind penetration) from 2016 to 2019 using quantile regression methods that provide a comprehensive picture of market conditions. Our findings demonstrate that the merit order effect exists for wind power supply expansion with unit revenue declines across all quantiles and generators. These declines occur consistently throughout market conditions but at different magnitudes. Each additional GWh of wind power is associated with a fall in wind revenue ranging from $0.01/MWh to $0.08/MWh. Wind power's cross-cannibalization effect also reduces gas and baseload capacity revenues across all quantiles, ranging from $0.02/MWh to $0.06/MWh per additional GWh of wind power. Interestingly, our results also reveal positive impacts of wind power supply on value factors (a measure of the energy's worth to the market) at low price market conditions, but negative impacts at high price conditions of the 95% and 99% quantiles. These findings confirm differential impacts of wind power across market conditions – more wind increases its worth at low market values but decreases its worth at high market values. Although the observed effects are exceedingly small, the findings of negative and unequal impacts on unit revenue in this research provide some insights and possible policy recommendations for energy market analysts, wind developers, and energy policymakers.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"36 6","pages":"Article 107303"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50177204","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}

Most industry observers believe that any improvement in the resilience of the U.S. electric-power network would be cost-beneficial. From an economic perspective, the desirability of improved resilience depends on the marginal benefits and marginal costs. Marginal benefits are especially hard to measure. There is also the question of whether utilities are applying the most cost-effective actions to improve resilience, which is difficult to judge but often ignored by state utility regulators in evaluating utility “resilience” plans. State utility regulators and electric system operators face the burden of answering to the heated public after an extended power outage. They will, not surprisingly, tend to err on the side of excessive resilience, which translates into higher electricity prices. Two probable explanations for this behavior are <em>probability neglect</em> and the <em>precautionary principle</em>. This essay concludes by posing less standard alternatives for policymakers to consider in addressing electric power resilience and the “outage” problem. Two alternatives are exploiting the price mechanism and compensating utility customers for extended power outages.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"36 6","pages":"Article 107304"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50177206","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}

This forecasting can help power supply companies to program their production or purchases. Based on this forecasting the companies take part in auctions that determine the price of the MWh in the electricity market and at the end of the day, the price for the end consumer. So far, the problem of forecasting power supply time series has mainly been dealt with the use of classical time series algorithms or VAR models. In this paper, we use a method from the insurance sector to forecast Greek power consumption hourly values. The innovation in this method is that it allows converting the forecasting of a system of time series (high dimensional time series) into forecasting a single time series and propagating the results back to each time series. It leaves the forecasting algorithm choice to the researcher, making it very flexible and removing the necessity of choosing complex algorithms. We demonstrate the forecasting of the results of this method by applying the ARIMA algorithm.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"36 6","pages":"Article 107305"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50177203","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}

Blackouts can be caused by failures in the energy distribution, errors in large power plants or even cyber-attacks. This can lead to a chain reaction and a disintegration of the mains. Longer blackouts have an extreme impact on the economy as a whole and on local households. Therefore, a small local grid at home which can supply the most important loads over some time has garnered increasing interest. With a small direct current (DC) grid, critical loads such as for deep freezers and refrigerators can be supplied, and some LED lights can be used in the evening or at night. Solar generators (panels) can be used to charge energy storage devices, e.g., batteries. A DC grid can not only be used in the case of an emergency, but can also be used to reduce energy consumption out of the public mains and reduce energy bills. The architecture of the household emergency DC grid is discussed; suggestions for batteries are given; two simple chargers, based on DC-DC-converters like the Buck (step-down) and on the Boost (step-up) converters, are shown; dimensioning suggestions are given; and simple, robust controllers, a P-controller with disturbance feedforward and a hysteresis controller, are treated and tested via simulations. The goal of the paper is to show a simple autonomous home energy system without an external fieldbus, LAN or internet connection with special focus on simple charger topologies.","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75449820","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}
