Abstract

In recent years, the rapid development of artificial intelligence, especially deep learning technology, makes machine learning have application scenarios in the fields of power system stability analysis, coordination along with scheduling and load forecasting. This paper designs an emotional deep learning programming controller (EDLPC) for automatic voltage control of power systems. The designed EDLPC contains an emotional deep neural network (EDNN) structure and an artificial emotional Q-learning algorithm. Besides, a specially defined proportional-integral-derivative (PID) controller is added to the deep neural networks (DNNs) structure as the actuator of an EDNN to realize the automatic tuning of PID controller parameters. In terms of control, the controller combines the advantages of the EDNN and PID controller, meanwhile adopts a reinforcement learning algorithm to optimize the parameters. From the perspective of reinforcement learning, embedding prior knowledge into the output instructions of EDNN is helpful to weaken the fitting problem in the training process. Compared with the outputs of the DNN and Q-learning algorithm under the two cases, the EDLPC could gain the highest control performance with smaller voltage deviations. The simulation results verify the feasibility and effectiveness of the proposed method for automatic voltage control of power systems.

Highlights

  • The conventional voltage control of the power system mainly includes three layers, which are the primary, secondary and tertiary levels of voltage control [1]

  • The traditional PID controller can ensure the stable operation of power system voltage control in the automatic voltage regulation (AVR) framework, there are still some deficiencies in power quality improvement

  • In the simulation of the last chapter, compared with the voltage deviation of 0.4222 generated by deep neural networks (DNNs) and the voltage deviation of 0.5615 generated by Q-learning, the 0.2007 voltage deviation obtained by emotional deep learning programming controller (EDLPC) proposed in this paper could ensure a better operation effect of the system

Summary

INTRODUCTION

The conventional voltage control of the power system mainly includes three layers, which are the primary, secondary and tertiary levels of voltage control [1]. The data of the emotional deep learning programming controller proposed in this paper comes from PID controller and provides a specific system model for simulation. This paper proposes an emotional deep neural network (EDNN) to improve the accuracy of voltage control, with strong nonlinear mapping ability. An EDNN is designed for the emotional deep learning programming controller (EDLPC), which can obtain a smaller voltage deviation in the power system through multiple neural layers. Both the Q-learning algorithm and the DNN have certain defects in the formulation of a control strategy.
