Method for definition of the real power limits and designation of distributed generation

Abstract

Distributed generation is already a reality in almost all countries in the world. Wind farms, cogeneration systems and SHP (small hydropower) are already common elements that can be connected to medium voltage systems (up to 15kV). Additionally, with the development of tecnologies and reduced costs, it is expected that the number of generations connected through the network increases, whether coming from solar collectors, biomass, SHP, wind turbine, or any other popular kind of generation in the future. Based on this premise, a new problem arises, what are the level of real power injection and best place for each connection to the network. The work proposed here aims to develop a method to determines the best connection point for each generation to the network and search the constraint of real power injection of each producer by which the greatest possible reduction of active power flow in its sections, ie, there is a reduction of the maximum load in each line.
