Distributed negotiation in future power networks: Rapid prototyping using multi-agent system

Abstract

Technologies like multi-agent system (MAS) have the capability to deal with future power grid requirements such as frequency management and voltage control under a flexible, intelligent and active feature. Based on web of cells (WoC) architecture proposed by European Liaison on Electricity Committed Towards longer-term Research Activity Integrated Research Programme (ELECTRA IRP), a distributed MAS with distributed negotiation ability for future distributed control (including frequency management and voltage control) is proposed. Each cell is designed as an intelligent agent and is investigated in case studies with constraints, where each agent can only communicate with its neighbouring agents. The interaction logic among agents is according to the distributed negotiation algorithm under consideration by the authors.Simulation results indicate that the WoC architecture could negotiate resources in a distributed manner and achieve successful exchange of resources by coordinating distributed agents. Moreover, the prototype reported in this paper can be extended further for future grids' distributed control regimes. The option of MAS to be exploited for the support of the development and integration of novel power system concepts is explored.Index Terms-Multi-agent system, negotiation algorithm, rapid prototyping, distributed control, agent communication.

Controller HIL testing of real-time distributed frequency control for future power systems

“…If the cell has either in excess or deficiency of reserves, the cell controller will inform its neighbor cells of its status (either excess or deficit of reserves) and at this point the intra-cell procurement negotiation phase will start. During this phase all the cell controllers will negotiate with their neighbors in a distributed manner similar to [9], where they will try to find the cheapest reserves from their neighbors taking into account the constraints of the system. The negotiation will finish once all the cells have managed to procure enough reserves, it is assumed that enough reserves will be available.…”

Systems Level Validation of a Distributed Frequency Control Algorithm

“…The validation of distributed algorithms has been addressed in literature. Typical validation attempts have been carried out in pure simulation environments (monolithic simulations, co-simulations and real-time simulations) [10]- [12]. In [5], [13], a controller hardware-in-the-loop (CHIL) approach was utilized for the validation of distributed control algorithms.…”

Design of a multi-agent system for distributed voltage regulation

“…MAS technology has received significant scientific interest in recent years in different fields of research, such as in power systems [10], [14][15][16][17][18][19]. Some practical applications of multiagent systems in the power industry and some of the key implementations are investigated in [16].…”
