Research efficiency of complex systems with spread spectrum renewable energy for electric power supply decentralized objects in Russia

Abstract

The urgency of using the integrated systems of renewable energy sources (RES clusters) within the significant area of the Russian Federation is demonstrated. The theoretical background of the methodology of cluster approach and substantiation of calculation of the optimal composition of the equipment of renewable energy sources within a RES cluster are presented. The analogy between the RES clusters and the Markowitz-Sharpe-Tobin portfolio theory is shown. The graphical model for searching for the optimal RES cluster and the algorithm of computation program are presented. The results of using various RES clusters for an experimental object "An Energy Efficient House" are considered. The resulting computed data and the experimental data demonstrate that the energy performance of optimized integrated systems (RES clusters) can be increased by up to 20-40% in terms of energy generation. The comparative performance of the existing RES cluster imported from China and the one optimized using the proposed methodology and the elaborated algorithm is shown. © 2014 WIT Press.
