Regimes Balancing in the Local Electric System with Renewable Sources of Electricity

Greater part of renewable energy sources is represented by solar electric stations (SES). Their operation mode depends on natural conditions of the region, where they are located. That is why the problem of RES stability estimation is important in the problem of covering the daily schedule of energy consumption. One of the aims of the research is to evaluate the probability of providing the consumption schedule by means of corresponding source on the base of statistic data. In this paper, the algorithm determination of stability covering load demand their own generation of renewable energy, particularly solar power, was proposed. On the basis of this indicator the method of determining the optimum by criterion of minimum reduced cost, power, which should provide a source of reserve to maintain an appropriate level of reliability in carrying the local electrical system. This method, based on the evaluation of stability data for generating renewable energy sources, including solar power, the problem of covering a given load demand and its impact on the number electricity.
