This paper proposes a multi-layer multi-agent model for the performance evaluation of power systems, which is different from
the existing multi-agent ones. To describe the impact of the structure of the networked power system, the proposed model consists
of three kinds of agents that form three layers: control agents such as the generators and associated controllers, information
agents to exchange the information based on the wide area measurement system (WAMS) or transmit control signals to the power
system stabilizers (PSSs), and network-node agents such as the generation nodes and load nodes connected with transmission
lines. An optimal index is presented to evaluate the performance of damping controllers to the system's inter-area oscillation
with respect to the information-layer topology. Then, the authors show that the inter-area information exchange is more powerful
than the exchange within a given area to control the inter-area low frequency oscillation based on simulation analysis.

A new coordination scheme for multi-robot systems is proposed.A state space model of the multi robot system is defined and constructed in which the system's initial and goal states are included along with the task definition and the system's internal and external constraints.Task accomplishment is considered a transition of the system state in its state space(SS)under the system's constraints.Therefore,if there exists a connectable path within reachable area of the SS from the initial state to the goal state,the task is realizable.The optimal strategy for the task realization under constraints is investigated and reached by searching for the optimal state transition trajectory of the robot system in the SS.Moreover,if there is no connectable path,which means the task cannot be performed successfully,the task could be transformed to be realizable by making the initial state and the goal state connectable and finding a path connecting them in the system's SS.This might be done via adjusting the system's configuration and/or task constraints.Experiments of multi-robot formation control with obstacles in the environment are conducted and simulation results show the validity of the proposed method. 相似文献

Enterprise systems must have the structure to adapt the change of business environment.When rebuilding enterprise system to meet the extended operational boundaries,the concept of IT city planning is applicable and effective.The aim of this paper is to describe the architectural approach from the integrated imformation infrastructure(In3) standpoint and to propose for applying the “City Planning” concept for rebuilding “inter-application spaghetti” enterprise systems.This is mainly because the portion of infrastructure has increased with the change of information systems from centralized systems to distributed and open systems.As enterprise systems have involved heterogeneity or architectural black box in them,it may be required the integration framework (meta-architecture)as a discipline based on heterogeneity that can provide comprehensive view of the enterprise systems.This paper proposes “EII Meta-model” as the integration framework that can optimize the overall enterprise systems from the IT city planning point of view.EII Meta-model consists of “Integrated Information Infrastructure Map(In3-Map)”,“Service·Framework” and “IT Scenario”.It would be applicable and effective for the viable enterprise,because it has the mechanism to adapt the change.Finally,we illustrate a case of information system in an online securities company and demonstrate spplicability and effectiveness of EII Meta-model to meet their business goals. 相似文献
