Real-time pricing of reactive power in the voltage profile control method of a future distribution network

It is of great importance to solve the voltage maintenance problem caused by the introduction of a large number of distributed generators. We have proposed a "voltage profile control method" using reactive power control for distributed generators, and in previous works we developed new systems that can provide economic incentives to owners of distributed generators who cooperate with voltage profile management. However, it is difficult to apply the proposed economic systems to real-time operation because they are based on optimization technology and the specific amount of incentive is given after the control action has ended. Therefore, in this paper we develop a new method that can determine the amount of incentives in real time and encourage the customers to cooperate with the voltage profile control method. The proposed method was tested in a one-feeder distribution network and its effectiveness was demonstrated.
