Abstract

The article discusses an algorithm for determining economically feasible places for connecting power supply systems with distributed generation sources to the external network. The algorithm is based on the dynamic programming method. The optimization criterion is the minimum costs for the purchase and transmission of electricity from external sources to local networks, while taking into account the reliability of electricity supply in the form of economic damage arising from both consumers and electricity suppliers. To find the optimal solution, models of electricity sources are used, which represent the dependence of the purchased power on the electricity tariff, power losses in the network elements and the reliability of power supply. When assessing the reliability of power supply, the features of the operating modes of the substation switchgear circuits, the substation equipment, the length and design of the power lines supplying the substation and extending to the power supply system under study are taken into account. The developed algorithm will allow determining the optimal points of connection to the external network, which will ensure the economical and reliable operation of power supply systems, and will also allow planning the power supply scheme at the design stage of a new or reconstruction of an existing network.

Keywords
