Microgrid Energy Management System for Reducing Required Power Reserves

Abstract

One of the promising directions for finding solutions to the problems of regimes management and commercial electricity accounting in electric power systems is the application of distributed ledger technologies - Blockchain, which is due to increased availability of renewable energy sources. Currently, in the Russian Federation, the use of Blockchain technology is difficult for electric power systems operating in parallel with regional or unified power system due to the legislative restrictions imposed on operations in the retail and wholesale market for electrical energy. However, based on the distributed ledger technologies, the principles of the functioning of the electric energy market can be applied within the framework of small isolated electricity systems - microgrids. Mathematical modeling and calculation of the microgrid electric regimes were performed in the RastrWin3 program with the aim of accounting for losses in the electric power system. During the simulation it was obtained dependence of the power at the slack node from the number of load nodes for a different ratio of own generation to consumption in the node. In the case of positive power, there was a shortage of actual power in the system at the slack node, and in the case of a negative one, there was an excess of it. The use of distributed generation is economically justified in small isolated electricity system: the payback period of distributed generation devices is much less than their lifetime. It is possible to use Blockchain technology to organize mutual settlements between owners of small generation facilities in microgrid.
