In Europe several issues may strongly impact on the power transmission system, posing new challenges to the TSOs (Transmission System Operators), whose role becomes more complex. The present paper results from some activities carried out within the European research project REALISEGRID, dealing with numerous transmission planning issues. After introducing the European context and reviewing the current...
The present status of transmission planning is reviewed from various viewpoints and the new requirements of transmission planning resulting from development of electricity markets are discussed. In the deregulated electricity market, there is no longer centrally coordinated planning of new generation or closure of existing generation, which are basically at the generation companies' own discretion,...
This is a panel presentation which is part of a full panel entitled "The Future Grid to Enable Sustainable Energy Systems." The presentation is a description of ‘Thrust area #1’ of a U. S. Department of Energy initiative on the future grid. Thrust area #1 is entitled “Electric Energy Challenges of the Future.” This thrust area relates to the design, operation, and conjectural configuration...
Transmission expansion planning (TEP) is a rather complicated process which requires extensive studies to determine when, where and how many transmission facilities are needed. A well planned power system will not only enhance the system reliability, but also tend to contribute positively to the overall system operating efficiency. Starting with two mixed-integer nonlinear programming (MINLP) models,...
Transmission expansion planning (TEP) is a complicated process that requires extensive studies to determine where, when and how many transmission facilities are needed. The fundamental concepts of TEP including the data, models, available software tools, as well as the technical skills needed for power system planning engineers are analyzed in this panel paper. Due to the amount of data in the bulk...
This paper presents a transmission expansion planning model which combines the advantages of both the traditional reliability-based transmission planning model and economic (also known as value-based, economics-based, or market-based) transmission planning model. Reliability-based transmission planning tries to install new lines at minimal cost while fulfilling system reliability criteria. Economic...
In the current study, the costs and benefits of deploying energy storage system (ESS) are discussed, and the role of ESS in transmission expansion planning (TEP) is investigated. Based on the classical formulation of TEP, a new formulation is developed considering the simultaneous addition of new circuits and installation of ESS. The fictitious costs of ESS are set instead of actual costs in the proposed...
