Active Disturbance Rejection Control of Microgrid DC-DC Converter Based on AC Algorithm

As an important part of the new power system, the stable operation of microgrid is very important for energy management and power supply reliability. As a key energy conversion device in microgrid, the stability and anti-disturbance ability of DC-DC converter directly affect the performance of the whole system. In order to solve the problem that some complex dynamic characteristics in DC microgrid affect the control effect of DC-DC converter and then affect the power quality of the whole system. In this paper, an ADRC strategy based on Actor-Critic (AC) algorithm is proposed. The self-tuning of LADRC parameters is realized by using the advantage of AC algorithm, and then the accurate control of DC-DC converter is realized. Secondly, the dynamic response characteristics and stability of the system under different control strategies are compared by simulation.
