Presenting a Stochastic Model of Simultaneous Planning Problem of Distribution and Subtransmission Network Development considering the Reliability and Security Indicators

Consumption growth demands power system expansion, and changes in a network lead to operation indices of the upstream network. Hence, establish reliable planning distribution network, simultaneous subtransmission should also be taken into account. It is predicted that this impacts different technical indices; therefore, formulation various need included model. Therefore, study, stochastic problem model super development considering reliability security indicators presented. The aforementioned form an optimization whose objective function minimize costs construction, replacement, operation, maintenance, reliability, security. Furthermore, mentioned bound equations distribution, voltage addition limitation indicators. worth mentioning that, proposed problem, active reactive loads operating price are uncertainty. Thus, which point estimation method used evaluate scenarios. Simultaneous expansion networks along with placement distributed generations capacitors, as well modeling indices, novelty scheme. In end, applied test by GAMS software, then capabilities extracted. Accordingly, based on numerical results, imposes considerable cost. Moreover, both helps its permissible range, lower loss, improve 100%.
