A Distribution Network Automation Terminal Configuration Method Considering Power Failure Loss and Power Supply Reliability

The main purpose of assembling automation terminals in the distribution network is to reduce the power outage time caused by permanent faults, reduce power outage losses and improve power supply reliability. Most of the traditional optimal configuration methods of distribution network automation terminals only aim to minimize power outage losses. However, in practical engineering applications, planners often want to minimize power outage losses and maximize power supply reliability. Therefore, this paper proposes an automatic terminal configuration method for the distribution network based on the epsilon constraint algorithm, which considers the power failure loss and power supply reliability. Calculation example analysis shows that this method can more intuitively understand the complex relationship between power outage loss and power supply reliability under different life cycle cost (LCC) constraints, which facilitates the smooth progress of optimal configuration work.
