Multiagent Control of DGs in Distribution Network for Active and Reactive Power Management

Abstract

The need for reduction of burning fossil fuels and CO2 emission has led to a change in how electrical power is being generated, transmitted and distributed. This has brought about the introduction of distributed generation units (DGs) mainly renewable energy resources as sources of power generation within the distribution network. With the growing use of distributed generations and energy storage devices across the distribution network, the architecture of the traditional grid faces challenges that threaten its safe and reliable operation. In this paper, the integration of PV and battery storage system is studied. Base models for a PV system and battery storage system were developed. The models were designed to ensure the generation of active and reactive power from the models and a multiagent control which includes a PV management system, battery management system and grid management system was developed to control the interaction between multiple DGs in the distribution network for efficient and reliable operation. Results from this study conducted via simulation show that battery storage systems are playing a big role in power management in the distribution network as they can absorb and produce both active and reactive power.
