Item Acesso aberto (Open Access) Despacho ótimo de redes integradas de energia elétrica e de gás natural com restrições de segurança via árvores de decisão(Universidade Federal do Pará, 2016-12-07) COSTA, Denis Carlos Lima; VIEIRA, João Paulo Abreu; http://lattes.cnpq.br/8188999223769913; NUNES, Marcus Vinícius Alves; http://lattes.cnpq.br/9533143193581447This thesis proposes the use of a decision tree (DT) based security dispatch method applied to integrated electric power and natural-gas networks (IPGN) against credible contingencies that may cause violations. Preventive adjustments to the optimal electric energy generation and gas production are carried out based on the security regions and boundaries of controllable variables determined by the DTs. The easily interpretable DT’s rules that describe the security regions are tractable constraints to be included in the optimization routines of electricity generation and gas production rescheduling. Some specific critical contingencies applied to the IEEE 118-bus test system integrated with the 15-node natural gas network are taken as examples to demonstrate a promising application of the proposed security dispatch method to restore IPGN security.
