Multiagent structures in hybrid renewable power system: A review

Abstract

Evolution in utility grid/electric grid from centralized control structures to decentralized control structures has been changed rapidly. Moreover this is because of increased usage of distributed renewable energy sources in utility grid. As a result this type of evolution necessitates new and advance concepts /methods in control structures of smart electric grid. Multi agent structures (MASs) are consequence of this requirement which is able to handle disturbances due to renewable energy sources, capacity to run in islanding mode, highly distributed nature of grid. Presently multi agent structures are the advancement of artificial intelligence. Agents facilitate a means to bridge the gap between humans and machines by means of interaction and intelligence. With the use of multi agent structures, optimization of control system and enhancement in reliability and intelligence may be realized. Main objective of the review is to give acquaintance of application of multiagent system in hybrid system so that in future it may form basis of multiagent system design with its pros and corns. Authors have discussed various aspects for development of multi-agent structures used in hybrid systems like system power control, optimization techniques with more emphasis on agent communication, agent platform, and MAS architecture. As agent platform and agent communication are the basis of any MAS construction. Proper selection of agent platform and agent communication decides easy and simple design of the MAS. Several aspects of MAS and its results are compared to provide global perspective of the state of the art.
