Abstract
| Future trends in the energy sector are crossing from centralized to distributed electricity production. A national and international organism encourages and informs consumers about the efficient use of energy. Such an approach of an efficient energy consumption lead to use of a certain number of renewable energy sources and a proper management of their. This paper, approach some issues of energy management and the use of unconventional sources of energy under the stochastic conditions. It showed a possibility of interconnection of renewable energy sources in a micro-smart grid. Four energy sources are proposed: the main source – power grid; secondary source 1 – photovoltaic generator; secondary source 2 – wind generator; secondary source backup 3 – diesel generator. The interconnection of these energy sources is achieved by a system of energy management and control based on a microcontroller structure type. Interconnection is based on the availability of energy sources and by energy consumption. The command and control algorithms for energy sources were implemented in Matlab Simulink software using specific functions and blocks. The energy management system ensures directing the flow of energy between sources and consumers. Also it manages the total energy distributed to consumers. The information can be stored and interpreted by a PC. |
