The research objective is to increase the locally consumed energy share by using two water tanks, aiming to shorten the breakeven periods of the renewable energy production devices. The shaved peaks from stochastic wind turbine and PV generation are fed into a preheating tank; the remaining excess power is fed into the main tank. The produced and consumed energies are in balance. The observed time period was one year with averaging time step 5 minutes. The annual PV/wind energy production share is assumed to be 30 %/70 % in favor of the wind. The anticipated result is to increase the renewable energy supply cover factor from 0.43 with a single heating tank up To 0.60 by deploying two tanks. If the same production peak shaving principles under the same conditions are applied seasonally, then The resulting supply cover factor can be augmented up to 0.69.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"11 1 1","pages":"106-110"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72674137","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 integration of these sources has impact on the load flow direction and magnitude. These changes can affect the operation of overcurrent (OC) relays as the main protective device in medium voltage (MV) distribution networks. In other words, the changes in the current magnitude and direction will result in misoperation of the OC relays during normal conditions of the network. In addition, the variation of the output generation of renewable sources due to weather condition changes, makes it difficult to define appropriate settings for OC relays. In this paper, a novel idea for improvement of OC relay operation in MV distribution networks in the presence of photovoltaic (PV) sources is presented. The proposed protection system is based on the augmentation of current and the reduction in voltage during the fault. Therefore, a combination of directional OC and undervoltage (UV) protection can distinguish between faulty and normal conditions. The proposed method is simulated using EMTDC/PSCAD software. The results show that the proposed method can effectively protect the MV distribution network containing PV sources.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"29 1","pages":"937-942"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86676492","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 study focuses on residential applications where the BMBES is installed at end-users premises and used for daily cycling under ToU and DC plans for saving on monthly electricity bills. Under the current U.S. electricity prices, different case studies of using two BMBES systems are discussed. The two systems are analyzed with practical load profiles of a two-story American family house. A number of ToU and DC plans from different utility companies and with different pricing structures are applied. First, the mathematical formulation of the monthly savings in the electricity bill is presented to determine the different technical and economic factors that affect the savings. Then, the System Advisor Model (SAM) software tool, which provides a techno-economic model of battery storage systems, is used for hourly, monthly, and annual analysis. In each scenario, the economic performance of the BMBES systems in terms of the cash flow diagram, net present worth and payback period is presented and discussed. Based on the analysis results, a set of implications on the profitability of the ToU energy arbitrage and DC reduction schemes under current prices of energy storage and electricity rates are stated. Such implications can be beneficial to customers and practitioners for selecting and designing residential electric rates.","PeriodicalId":6535,"journal":{"name":"2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"54 1","pages":"842-849"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90980593","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}
