Item Analysis of the connection of a microturbine to a low voltage grid(IEEE Computer Society, 2005) Amorim, A.; Cardoso, A. L.; Oyarzabal, J.; Melo, N.; POWER SYSTEMSExpected advantages to Customers, to utilities and to environment, from the connection of a microturbine to a low voltage grid, are presented. The main components and loads of the designed microgrid are characterised, and some performance results that shall be achieved on the system are presented. Furthermore, some technical challenges are focused to emphasise the microgrid implementation barriers in the Portuguese study case.Item Distributed generation scheme analysis, as an option for Bogota electrical system(2012) Balaguera, Daniel Alberto; Cortes, Andres Felipe; Uruena, Mauricio Alexander; POWER SYSTEMSThis paper outlines the analysis of the concept in the implementation of distributed generation systems focused on the city of Bogotá. Different experiences of adoption of this type of generation, that could be located in various parts of the city, with special emphasis on the economic, environmental, and improved reliability of electricity supply, reported by different authors. Similarly, it also presents a characterization of Colombian electricity sector, through a historical overview of its evolution to its current state, applying the concept of distributed generation. Finally, define benefits and disadvantages of the implementation of distributed generation in Bogota, to be applied to obtain an effective and permanent positioning of these technologies in power schemes in other regions of the country. The conclusion, about the possibility of implementing distributed generation systems under conditions of government stimulus for the development of technologies based on renewable energy generation and cogeneration.Item Optimised TSO-DSO Coordination to Integrate Renewables in Flexibility Markets(IEEE, 2019-09) Madina, Carlos; Kuusela, Pirkko; Rossi, Marco; Aghaie, Hamid; Gomez-Arriola, Ines; Riaño, Sandra; POWER SYSTEMS; SISTEMAS FOTOVOLTAICOSThe necessary energy transition to decarbonize power systems is leading to increasingly important challenges for the operation of power systems. On the one hand, the intermittent nature of renewable generation requires system operators to procure ancillary services in larger volumes than in the past. On the other, the growing penetration of medium- and small-scale, flexible demand and storage systems in distribution networks could potentially offer network services, if they are aggregated effectively and there is an appropriate coordination between transmission system operators (TSOs), distribution system operators (DSOs) and aggregators. Therefore, an important topic to be analysed is whether distributed energy resources (DER) can replace traditional generation in the provision of ancillary services (AS), how this replacement will affect the system operators’ roles and how to improve the coordination between TSOs and DSOs. This paper shows the results of the cost-benefit analysis (CBA) performed within the project SmartNet to assess the advantages or disadvantages of different TSO-DSO coordination schemes, as well as the follow-up activities to be carried out in the project CoordiNet.
