Optimal Configuration of Measurement and Control Devices in Distribution Network Based on Life Cycle Cost

Reasonably configuring the measurement and control devices represented by the distribution terminal and micro-phasor measurement unit ($\mu$PMU) can improve the power supply reliability of the distribution network. Considering the devices costs and outage losses within the life cycle of devices, this paper proposes an optimal configuration model for measurement and control devices. Taking the average annual power outage time of users as the index of power supply reliability, the impact of the measurement and control devices on the power supply reliability is analyzed. Then take the lowest economic cost of distribution network in the life cycle of devices as the objective, and the genetic algorithm is used to solve the optimal configuration model. Finally, the proposed model is applied to an IEEE RBTS BUS-2 test system. The results show that the proposed model can achieve the best economic efficiency on the basis of ensuring the power supply reliability, and the effectiveness of the model is verified.
