Optimization of power streams in self-sufficient system of power supply with nonconventional power sources

Article describes definition of energy resources uses level at which energy consumption reaches the minimum value. On the example of an self-sufficient power supply system of a small village including some renewable energy sources and an alternate energy source parameters of an selfsufficient power complex are proved, and the structure of power streams is optimized by using of mathematical modeling methods, which are the most reliable and valid. For the research of the questions connected with structure optimization of power streams, system approach is used at a choice of decisions, at which the object is considered as the difficult system consisting of elements set, work of each element is optimized taking into account its communication with other elements and influence on object work as a whole. The solution of optimization problem is carried out by means of analytical and numerical methods, optimum power streams and the specific annual given charges as a result are defined. The problem is solved by a method «branches and borders» discrete programming.
