In the hierarchical control of an islanded microgrid, secondary control could be centralized or distributed. The former control strategy has several disadvantages, such as single point of failure at the level of the central controller as well as high investment of communication infrastructure. In this paper a three-layer architecture of distributed control is given, including the device layer, the control layer as well as the agent layer. The agent layer is a multi-agent system in which each agent is in charge of a distributed generation unit. Due to communication network constraints, agents are connected only to nearby neighbors. However, by using consensus algorithms the agents can discover the required global information and compute new references for the control layer. The proposed control system is tested on a microgrid scenario which includes paralleled inverter sources. For this, the system is implemented on a real-time cyber-physical test platform that combines real-time simulation models running in OPAL-RT with a network of ARM-based computers, representing the agents.

nowadays, developing electric vehicles (EVs) is an important measure to reduce the greenhouse effect of the traditional transportation system. While the number of EVs growing rapidly, how to charge EVs efficiently attracts researchers' attention. Different from the traditional centralized charging power allocation, which is operated by a centralized control computer collecting all information and sending the commands to EVs, in this paper the decentralized power allocation strategy for EV charging network is proposed. Moreover, the centralized algorithm requires a high quality communication network, which cannot handle disturbances in communication like delays or packet losses. Therefore, the consensus algorithm is applied here to realize the efficiency and robust power allocation of the EV charging network in a decentralized fashion. The effectiveness of the proposed strategy has been fully investigated in three different cases.
We study the problem of an organization that matches agents to objects where agents have preference rankings over objects and the organization uses algorithms to construct a ranking over objects on behalf of each agen...
