Currently, with the increasing incentive to use alternative and renewable sources of energy, the number of generators connected to the electricity distribution networks has increased. Among them are, for example, wind farms, photovoltaic solar energy systems and cogeneration systems forming a so-called Distributed Generation.
Faced with this global scenario, it is imminent the need to develop new technologies and computer programs that allow the optimization of generator connections during the real-time (online) operation of the electrical system. This should be done in such a way that, among other advantages, control strategies are improved and efficiency increased.
This work proposes the creation of an algorithm to assist in the management of the online operation of electricity distribution networks with distributed generation. It must be developed in a way that processes the information in short time intervals, so as to enable its real-time application in the system. Basically, this computational tool calculates the optimal dispatch of the distributed generation in the network bars, helping the operator and / or systems in faster and more precise decision making.
Because it is a problem in which the search space is large and with the possibility of local minimums, it was decided to use some optimization methods, such as the Gradient and Lagrange methods, which are more suitable for this type of problem. Through its application, it is possible to find the optimal point of operation of the network in real time, in order to optimize the technical losses of the system. For the simulation of the system, we chose the Power Sum load flow method, developed for medium voltage radiated systems and presenting a fast and accurate convergence.
