Previous issue date: 2017-02-16 / Pontif?cia Universidade Cat?lica de Campinas ? PUC Campinas / This study proposes the development of an environment for optimization of the operations of electrical distribution systems. The environment is proposed for the modern electrical distribution networks considering the possibility of inclusion of distributed generation and mesh topology. The environment is divided into three modules. The first module consists of standardizing the input and organization data of the network in memory using techniques of object-oriented software engineering. This approach simplifies the processes of nodal analysis of the circuits, improves the performance of the solution and allows reusing the objects and operations in other implementations. The second module is responsible for analyzing and represents network characteristics: topology, load model and distributed generation points. The third consists of the BFS, FW and OCF methods to perform the current flow calculation and allows the user to choose the desired algorithm, being able to present the currents and voltages in each iteration. The choice of different methods in the optimization environment allows the use of the most adherent method to the different network topologies, the types of load, the flexibility in the use of capacity constraints of the elements of the network and the inclusion of generation limits and voltage limits. In order to verify the adhesion and the efficiency of the environment, simulations were carried out on balanced three-phase circuits of primary distribution of 11, 33 and 400 buses with different load models, radial or mesh topology, with and without distributed generation. / Esta pesquisa prop?e-se ao desenvolvimento de um ambiente para otimiza??o da opera??o de sistemas de distribui??o de energia. O ambiente ? aderente ?s modernas redes de distribui??o de energia por considerar a possibilidade de inclus?o de gera??o distribu?da e topologia em malha. O ambiente est? dividido em tr?s m?dulos. O primeiro m?dulo consiste na padroniza??o dos dados de entrada e organiza??o da rede em mem?ria no formato de grafo utilizando t?cnicas de engenharia de software orientada a objetos. Este enfoque simplifica os processos de an?lises nodais dos circuitos, melhora o desempenho da solu??o e permite reaproveitar os objetos e opera??es em outras implementa??es. O segundo m?dulo ? respons?vel pela an?lise e representa??o das caracter?sticas da rede: topologia, modelo de cargas e pontos de gera??o distribu?da. O terceiro consiste dos m?todos BFS, FW e OCF para a execu??o do c?lculo do fluxo de corrente e d? a op??o ao usu?rio de escolha do enfoque desejado, podendo apresentar as correntes e tens?es em cada itera??o. A op??o de escolha de diferentes m?todos no ambiente de otimiza??o possibilita o uso do m?todo mais aderentes ?s diferentes topologias de rede, aos tipos modelos de carga, a flexibilidade no uso de restri??es de capacidade dos elementos da rede e a inclus?o de limites de gera??o e limites de tens?o.
Com a finalidade de comprovar a ader?ncia e efici?ncia do ambiente foram realizadas simula??es em circuitos trif?sicos equilibrados de distribui??o prim?ria com 11, 33 e 400 barras com modelos de carga constante, topologia radial, anel, com e sem gera??o distribu?da.
