This paper discusses various AS market design options for procuring, pricing and settling ancillary services via competitive auctions by an independent system operator (ISO). The paper also discusses problems and potential solutions associated with these market design options based on actual experience of operating ISOs. These problems include price volatility and spikes and price reversals for the various components of the ancillary services that can create perverse incentives in the marketplace. Further we elaborate on the design that has been proven so far based on practical experience to be the most efficient.","PeriodicalId":380613,"journal":{"name":"2007 IEEE Power Engineering Society General Meeting","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129416087","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}

However, small distributed generation (DG) systems using renewable energy have not yet achieved a significant level of penetration. With deregulation of electricity market, policies have been available to facilitate interconnection of small distributed generators (DGs) with electric grids. However, dispatchability and reliability still present technical barriers for small DGs to play a significant role in the open market, thus limiting their ability to provide value-added services. This paper presents a new concept to enhance the dispatchability of DGs through an aggregated DG network. Dispersed DGs with different energy resources, such as wind turbines, photovoltaics, small hydros, fuel cells, and microturbines, are integrated into a single aggregated generating plant via open power transmission networks. Traditional SCADA dedicated optical fibers, copper and other dedicated wireless physical layers can be replaced by Internet access and low-cost point-to-point wireless communication links to reduce infrastructure costs. The aggregated power generation is balanced between firm DGs and intermittent DGs to allow for the required dispatchability. Day-ahead and hourly generation scheduling can be committed in wholesale electricity trading, thereby achieving the desired added economic benefits. This is usually more favorable than being credited at the avoided cost as seen by utilities with traditional individual DGs.","PeriodicalId":380613,"journal":{"name":"2007 IEEE Power Engineering Society General Meeting","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128448894","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}

Simulation results show a grounding fault in the middle of the line exhibiting maximum voltage with value of 1.54 p.u, which agrees well with the theoretical value. And the maximum voltage decreases with the increasing grounding resistance. The inductance of the reactor influences the maximum voltage on health line a little.","PeriodicalId":380613,"journal":{"name":"2007 IEEE Power Engineering Society General Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128760791","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}

Non-sinusoidal voltage has detrimental effects on induction motors performance; hence derating of the machine is required. Thermal models used in protective relays are based on pure sinusoidal waveform, which could not effectively protect the motor if the supply voltage waveform is distorted. In this paper a new thermal model is proposed that not only protects the motor from overload under normal power supply condition, but also applies a proper derating factor under waveform distortion. The modified model evaluates the thermal limitations of the stator and rotor together and protects the motor in the presence of excess overheat. Under distorted waveforms, the trip threshold is indicated by the level of distortion in addition to the service factor. The simulation results indicate the effectiveness of the model in the presence of different harmonics.","PeriodicalId":380613,"journal":{"name":"2007 IEEE Power Engineering Society General Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129369242","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}

It adopts digital optical communication technology and Ethernet network instead of traditional metallic cable. Therefore it can highly enhance the anti-interference ability and reliability of the protections. The hardware structure and software pattern are introduced respectively. The new protection adopts the high-speed DSP TMS320VC33 as its hardware platform and RTL8019AS as the Ethernet controller. Task scheduling is based on multi-task mechanism. Ethernet communication task's priority is lower than the sampling task and the protection task but higher than the keyboard and display tasks. Switches among tasks are realized by dispatching and receiving signals. Some performance test results are presented in the end and prove the new protection's potential to be realized in the field in future.","PeriodicalId":380613,"journal":{"name":"2007 IEEE Power Engineering Society General Meeting","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129663784","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}
