Early in 2011, the CIGRE Technical Committee decided to increase the focus and coordination of its work in relation to energy efficiency, in recognition of the importance of this issue. Within a global context, this paper will summarise the framework that is being used to guide the CIGRE work and describe current findings and future opportunities to address the high priority areas. Drawing on the work of the sixteen Study Committees of CIGRE that cover aspects ranging from plant and equipment through to overall system planning and operation, the paper will describe the strategic approach that is being used to connect the various aspects of the work. A particular focus will entail analyses and commentary on four technical areas in which CIGRE is positioned to provide expert advice on international and national approaches towards energy efficiency. These are: high efficiency equipment (including the contribution offered by standardization), emerging technological options, new network topologies (in a integrated frame, to improve the overall system performance and efficiency), and energy storage. How these tools can be practically deployed to the power system will then be examined with regards to incorporating sustainability concerns into long-term decision making. Also the need of rigorous and carefully applied metrics, to evaluate the costs and benefits of efficiency improvement, will be addressed. The paper proposes that raising awareness of potential directions and their associated benefits from an impartial information source such as CIGRE will enhance national and international approaches towards energy efficiency.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"7 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84956636","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 has the potential to play an important role in a future renewable energy market. However, wind power is neither continuous nor stable because of the natural fluctuation of wind energy and the nonlinear relationship between power output and wind speed. Wind power is therefore considered to be unreliable when comparing it with conventional power generation sources. In addition, fluctuating wind power leads to significant state variations in the power system. In rural distribution systems, voltage fluctuation is one of the main disturbances which must be examined at the generation connection impact assessment stage. In this paper, first of all, the relationship between the voltage at the Point of Common Coupling and the power contributions by a Distributed Generator will be introduced. Second, a typical rural distribution system will be modeled in a simulation software. Then, different scenarios will be simulated to analyze several steady-state and dynamic impacts of Distributed Generators on distribution networks. Finally, different impact mitigation solutions will be presented.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"58 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82564332","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}

Vinodkumar","doi":"10.1109/TDC.2012.6281631","DOIUrl":"https://doi.org/10.1109/TDC.2012.6281631","url":null,"abstract":"The first real time task of ISO focuses on Static Congestion Management (SCM), i.e. the congestion caused by the thermal and voltage limits. When power systems undergoes discrete changes in system configuration due to outage and contingencies, the system dynamic performance will be affected and the system stability might be threatened. In this respect, the second real time task of ISO focuses on the utilization of available resources to maintain system security and reliability. This process is called Dynamic Congestion Management (DCM). The DCM refers to the process that secures stability of the post fault power system in an economic manner. The objective function of the DCM model used in this paper has been formulated as a constrained nonlinear optimization problem. This proposes the application of Real Coded Genetic Algorithm (RCGA) for solving the constrained nonlinear DCM model to assess the generation re-scheduling for minimizing the objective function. In the proposed RCGA method, owing to the adaptive capability, Simulated Binary Crossover (SBX) and Tournament selection is used as selection mechanism in order to avoid premature convergence. To establish the linear inequality of transmission limit constraints and transient stability constraints, generator shift factor and trajectory sensitivities are calculated. The algorithm's performance has been examined over 3-machine, 9-bus WSCC system.","PeriodicalId":19873,"journal":{"name":"PES T&D 2012","volume":"64 3 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2012-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89723172","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}
