This paper employs modelling to show that through control device manipulation, gas and electric (G&E) network operators can influence savings in energy losses under the presence of plug-in hybrid vehicles (PHEVs) and combined heat and power technologies (CHPs). An integrated gas and electric optimal power flow (OPF) tool is introduced to undertake various case studies. The OPF tool evaluates the technical impacts experienced in the networks when DNOs apply a “plug and forget” operation strategy and then compares the results against a “loss minimisation” strategy. Results show the benefits in applying different strategies are more considerable in electric networks than in gas networks. The study corroborates that an integrated G&E analysis offers a fresh perspective for stakeholders in evaluating energy service networks performance under different operation strategies.","PeriodicalId":211685,"journal":{"name":"2009 IEEE PES/IAS Conference on Sustainable Alternative Energy (SAE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123772814","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 standard operation paradigms, a power system is seen as some equivalent of a synchronous generator, a power line and an uncontrollable load. This paradigm is being questioned by a diverse mix of challenges posed by renewable energy sources, demand response technologies and smart grid concepts, affecting all areas of power system operation. Both, new control modes and changes in market design are required eventually. A proper redesign should starts with a coherent approach to modeling. This paper presents a mean-ends perspective to the analysis of the control structures and operation paradigms in present power systems. In a top-down approach, traditional frequency-and area-control mechanisms are formalized. It is demonstrated that future power system operation paradigms with different generation control modes and controllable demand can be modeled in a coherent way. Finally, the discussion is opened up toward a formalization of service-exchange between market participants.","PeriodicalId":211685,"journal":{"name":"2009 IEEE PES/IAS Conference on Sustainable Alternative Energy (SAE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124169830","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 considered region is subdivided into its settlement units to form the levels. Each level comprises distinct conversion technologies to supply the load. The power supply is composed of various energy carriers, like electricity, gas and heat, in order to exploit synergy effects. Renewable and conventional power plants produce the demanded heat and electricity. The optimal power supply policy for the region is determined applying a bottom-up optimization approach. Optimality is defined by either minimum costs, or minimum emissions that are necessary for the proposed supply strategy. Two prospective scenarios are examined and compared with respect to their costs, the use of different energy carriers, and their environmental impacts. Depending on the implemented scenario, primary grid-energy demand decreases more significantly than final energy demand because of synergy effects.","PeriodicalId":211685,"journal":{"name":"2009 IEEE PES/IAS Conference on Sustainable Alternative Energy (SAE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132379484","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}

Two main modules compose this framework: the characterization of one isolated load and the study of different loads connected at the same time. For the characterization of one simple load empiric data from real time impedance was analyzed. The study of two loads connected at the same time was used as a validation test. For both stages typical in-home appliances were selected. The conducted work aims to be a useful tool for improving flexibility and hence allow demand response programs.

By using the proposed algorithm, a more efficient network configuration can be obtained to reduce loss. The problem is optimized in a stochastic searching manner similar to that of the evolutionary programming (EP). The initial population is determined by opening the switches with the lowest current in every mesh derived in the optimal power flow (OPF) with all switches closed. To avoid prematurity, HP technique was applied to adjust the number of mutant elements adaptively. Tabu Lists with heuristic rules were employed in the searching process to enhance performance. Simulation results show that the proposed algorithm has advantages than the earlier developed algorithms. The optimization strategy is general and can be used to solve other power system optimization problems as well.","PeriodicalId":211685,"journal":{"name":"2009 IEEE PES/IAS Conference on Sustainable Alternative Energy (SAE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125508400","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 reduce the reverse power flow from PV power systems, energy management by use of storage batteries is expected to be a solution. In addition, the combination with load control is expected to reduce the storage capacity. In this study, energy management methods by use of the Supply and Demand Interface (SDI), which is a device to control DG, batteries and loads, are proposed and the effectiveness of the methods are evaluated by simulation analyses. The simulation results show that the amount of reverse power flow from PV power systems is reduced by the proposed energy management methods, and the load control is effective in reducing the reverse power flow. The required storage capacity to prevent the reverse power flow from the distribution line to the transmission line is also shown.","PeriodicalId":211685,"journal":{"name":"2009 IEEE PES/IAS Conference on Sustainable Alternative Energy (SAE)","volume":"84 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122418462","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}
