Intelligent control for a distributed flexible network photovoltaic system using autonomous control and agent

Abstract

This paper proposes intelligent control for a distributed flexible network photovoltaic system using autonomous control and agents. The distributed flexible network photovoltaic system is composed of a secondary battery bank and a number of subsystems which have a solar array, a DC/DC converter, and a load. The control mode of the DC/DC converter can be selected based on local information by autonomous control. However, if only autonomous control using local information is applied, there are some problems associated with several cases, such as voltage drops on long power lines. To overcome these problems, the authors propose introducing agents to improve the control characteristics. The autonomous control with agents is called intelligent control in this paper. The intelligent control scheme that employs communication between agents is applied to the model system and validated by simulation using PSCAD/EMTDC.
