Supplying a transformer much larger than necessary to a customer adds capital costs to a project, as well as increased future costs of transformer losses. Under-sizing a transformer for a client leads to reliability issues and an unsatisfied customer. Analysis shows the financial benefits of accurately sizing transformers, based on a study conducted on a group of three-phase pad-mounted transformers at Black Hills Power Utility in Rapid City, SD. By researching existing customer electricity use, a method of forecasting electricity load is developed and applied.","PeriodicalId":433119,"journal":{"name":"2009 IEEE Rural Electric Power Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122990978","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}

Distribution circuits are designed to supply radial loads. Therefore, the introduction of green generation can result in: redistribution of fault and load currents on the feeder circuit, overvoltage and ferroresonance, plus a possible loss of protection system coordination—all of which can result in customer outages. The paper also discusses the specific reliability and protection issues in interconnecting green power generators to utility systems to mitigate the above cited reliability issues. These issues are not adequately discussed in IEEE standard 1547, which addresses interconnection of DG to utility systems.","PeriodicalId":433119,"journal":{"name":"2009 IEEE Rural Electric Power Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131680931","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}

Distributed energy resources (DER) are not commonly connected to a bulk power transmission system, instead are interconnected near the load in the electric power distribution system. DER includes renewable energy such as wind and solar, fossil-fuel based generation such as microturbines, small gas turbine units and distributed energy storage. In this paper, a novel methodology is developed that ranks utility feeders for implementation of DER systems. This performance index is based on peak load reduction, increased system capacity, load-generation correlation, and feeder load growth. This is based on a statistical measure that quantifies the relationship between loads and the stochastic nature of renewable resources. This allows the utility to gain insight into improved benefits from non-dispatchable renewable resources such as solar and wind technologies as well as dispatchable DER technologies.","PeriodicalId":433119,"journal":{"name":"2009 IEEE Rural Electric Power Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128656147","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 paper will describe how multiple variable inputs into the software will allow for alternatives to have different initial costs, variations in future operation and maintenance expenses and different levels of future loss costs. The body of the paper will describe how such a tool can allow an end user to quickly and efficiently evaluate different conductor sizes, changes in number of phases, different types of line construction (i.e., underground versus overhead) as well as evaluating “what if” cases using different purchased power cost and maintenance escalation rates. It will also discuss how a user might choose to report the results using a simplified single result, matrix or visual comparison. The paper will conclude by illustrating how this or similar types of software can expedite complex engineering and economic evaluations to assist management in making decisions regarding system improvements.","PeriodicalId":433119,"journal":{"name":"2009 IEEE Rural Electric Power Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129864126","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 use and coordination of these capabilities can result in immediate CVC programs that can affect the average electric power consumer voltage level. The implementation of proposed SG (SMART GRID) system features will further increase the accuracy and effectiveness of such programs. Recent studies have shown that the single act of reducing the average consumer voltage levels within the acceptable voltage range (114–126 volts) results in significant positive changes on the power system. These system benefits will be shared by the consumer with lower power bills and by the utility in lower losses, reduced fuel costs, increased equipment capability, reduced need for power factor correction equipment, delayed new generation requirements, and more. A loss of revenue for the utility will occur, as it does for any power efficiency or conservation activity.","PeriodicalId":433119,"journal":{"name":"2009 IEEE Rural Electric Power Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115565624","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}
