From Microgrids to Smart Grids: Modeling and simulating using graphs part II optimization of reactive power flow

The Smart Grid of the future will be created starting from Smart Microgrids. The modeling of Microgrids and the simulations of their real time steady state status is presented in the paper. The model is created using graphs. This paper continues a previous one, which dealt with the active power flow. This time the reactive power flow and its optimization are considered. A Windows type application created based on the model is presented. This powerful tool can be used to evaluate the total loss when an electrical network based on RES has to be designed. It can be used to optimize the links between nodes, the reactive power control devices optimal placement and optimal reactive power generation/compensation. From these operations result decreased losses (costs).
