Optimisation Problem of Bi-current System of Distribution Generation

The paper analyses the main problems of the use of electric energy, taking into account the trends of the evolution of modern electric power systems. Arguments are given in favour of the intensive development of a distributed generation. The circuit of a bi-current system, which is the most promising variant for the distributed generation, is considered. An objective function of the optimization has been formed for it, which is represented by the dependence of the efficiency on the DC link voltage. The analysis of the calculations, based on a typical example of the parameters, has shown that the most optimal voltage values are 110 V and 220 V for the DC link. At these voltage values, the region of the maximum possible values for the efficiency is reached.
