Abstract

An additional (generation) source of reactive power may be required in a backbone network node (𝑈௡ ≥ 220 𝑘𝑣) which has a heavy reactive load. When solving this problem, in a technical-economic sense, it is advisable to place this additional source of reactive power not in the mentioned node of a backbone network, but in the nodes of a distribution network (𝑈௡ ≤ 110 𝑘𝑣) connected to this node. This problem specifically involves: optimal rescheduling of total power of the additional reactive power source selected according to a voltage criterion in a backbone network node between the distribution network nodes connected to this node. The relevant optimization equations created in the article and the obtained mathematical model allow us to solve this problem effectively and successfully. The condition for optimality here implies the best economic returns, while the objective function is to minimize active power losses caused by nodal reactive powers. That was why we used the economic criterion as the main criterion in solving this problem.
