Abstract
The paper presents an approach for short-term planning of the development of distribution networks in the presence of decentralized energy sources (DES). The approach consists in developing planning strategies with the aim to control the electrical network and in compiling a number of scenarios to each strategy. The stages of construction of the decentralized sources and the possibility of changing the electrical loads are taken into account. Calculations of the parameters according to the selected one or several criteria for the different scenarios of each strategy allow to choose the optimal one from the whole number of 196 developed scenarios. This is an actual problem in planning the distribution networks with connected decentralized energy sources. The paper presents the developed calculation modules, together with the specialized software for the simulator of the modes in the electrical networks. The compiled algorithm allows to determine the optimal scenario for short-term planning of a distribution network with set loads and decentralized energy sources, while taking into account the most significant influencing factors and limitations. It is not possible to point in advance for a particular branch of a distribution network at the optimal scenario for a given strategy by a chosen criterion. Therefore, it is necessary to perform the calculation procedures by the proposed methodology and software.
