Estado del arte de la planeación de expansión de sistemas de transmisión

The growth of demand in electric power systems has created the need for expansion at all levels, the problem of planning the optimal expansion of electric transmission systems, considering all the factors and restrictions that are involved as: reliability, maximum chargeability, angular deviation, voltage profile, resolution method, contingencies and system loss; in search of an optimal expansion of the transmission systems the present investigation is oriented towards the method of optimal power flow AC; Therefore, gathering information of relevant scientific articles was carried out that would be the basis of the beginning of future research, allowing to strengthen the transmission system at low cost , in order to maintain the power electrical system with stability and reliability.El crecimiento de la demanda en los sistemas eléctricos de potencia ha creado la necesidad de la expansión en todos sus niveles, el problema de la planeación de la óptima expansión de los sistemas eléctricos de transmisión es, considerar todos los factores y restricciones que se involucran como: confiabilidad, cargabilidad máxima, desviación angular, perfil de voltaje, método de resolución, contingencias y pérdida del sistema; en busca de una óptima expansión de los sistemas de transmisión la presente investigación es orientada hacia el método de flujos óptimos de potencia AC; por lo tanto, se realizó un levantamiento de información de artículos científicos relevantes que permitan ser la base del inicio de futuras investigaciones, permitiendo robustecer el sistema de transmisión a bajos costo, con el fin de mantener el sistema eléctrico de potencia con estabilidad y confiabilidad

Optimization Methods Applied to Power Systems Ⅱ

Electrical power systems are complex networks that include a set of electrical components that allow distributing the electricity generated in the conventional and renewable power plants to distribution systems so it can be received by final consumers (businesses and homes). In practice, power system management requires solving different design, operation, and control problems. Bearing in mind that computers are used to solve these complex optimization problems, this book includes some recent contributions to this field that cover a large variety of problems. More specifically, the book includes contributions about topics such as controllers for the frequency response of microgrids, post-contingency overflow analysis, line overloads after line and generation contingences, power quality disturbances, earthing system touch voltages, security-constrained optimal power flow, voltage regulation planning, intermittent generation in power systems, location of partial discharge source in gas-insulated switchgear, electric vehicle charging stations, optimal power flow with photovoltaic generation, hydroelectric plant location selection, cold-thermal-electric integrated energy systems, high-efficiency resonant devices for microwave power generation, security-constrained unit commitment, and economic dispatch problems

Fuelling the zero-emissions road freight of the future: routing of mobile fuellers

The future of zero-emissions road freight is closely tied to the sufficient availability of new and clean fuel options such as electricity and Hydrogen. In goods distribution using Electric Commercial Vehicles (ECVs) and Hydrogen Fuel Cell Vehicles (HFCVs) a major challenge in the transition period would pertain to their limited autonomy and scarce and unevenly distributed refuelling stations. One viable solution to facilitate and speed up the adoption of ECVs/HFCVs by logistics, however, is to get the fuel to the point where it is needed (instead of diverting the route of delivery vehicles to refuelling stations) using "Mobile Fuellers (MFs)". These are mobile battery swapping/recharging vans or mobile Hydrogen fuellers that can travel to a running ECV/HFCV to provide the fuel they require to complete their delivery routes at a rendezvous time and space. In this presentation, new vehicle routing models will be presented for a third party company that provides MF services. In the proposed problem variant, the MF provider company receives routing plans of multiple customer companies and has to design routes for a fleet of capacitated MFs that have to synchronise their routes with the running vehicles to deliver the required amount of fuel on-the-fly. This presentation will discuss and compare several mathematical models based on different business models and collaborative logistics scenarios

International Conference on Continuous Optimization (ICCOPT) 2019 Conference Book

The Sixth International Conference on Continuous Optimization took place on the campus of the Technical University of Berlin, August 3-8, 2019. The ICCOPT is a flagship conference of the Mathematical Optimization Society (MOS), organized every three years. ICCOPT 2019 was hosted by the Weierstrass Institute for Applied Analysis and Stochastics (WIAS) Berlin. It included a Summer School and a Conference with a series of plenary and semi-plenary talks, organized and contributed sessions, and poster sessions. This book comprises the full conference program. It contains, in particular, the scientific program in survey style as well as with all details, and information on the social program, the venue, special meetings, and more
