  Holonic structures are a hierarchical formation of holons that are developed and used for the purpose of restricting interaction domains, reducing uncertainty, or forming the high level goals of multi-agent systems, in such a way that the system benefits a high degree of flexibility and dynamism in response to environmental changes. Although the holonic multi-agent systems are extensively used in modeling and solving complex problems, most of its prerequisites, like forming the body holons and dynamically controlling its structure, use very simple application-specific models. This is due to the immaturity of the research literatures in this field. In this article, an endeavor is made to propose a goal-based approach for the formation of holonic structures, using the concepts in social science and organizational theory. The use of concepts like role, skill, and goal structures, makes the proposed method possible to be used in wide range of applications. In order to demonstrate the capabilities of the method and also the way it can be applied in real world problems, a test bed based on the application of wireless sensor networks in object tracking is designed and presented. In this application, the sensors, which are distributed in the environment as simple agents, using holonic structures, are responsible for the track of any alien objects that enter and move in the environment. According to the empirical results of the simulations, the proposed holonic approach has provided successful performance in terms of tracking quality and energy consumption of the sensors.

  In this paper, a new energy management strategy is presented by using shunt active power filter (SAPF) in a multi-agent structure. This strategy is applied to a micro-grid connected to the grid and includes the problem of harmonic compensation. By examining the advantages and disadvantages of shunt active power filters and passive filters, as well as their efficiency in the multi-agent structure for power micro-grids, the reason for using shunt active power filters in the proposed method has been determined. Also, the performance of these filters for compensating current harmonics has been compared by examining the FFT results. In the used micro-grid, wind turbine generator and solar cell generator are used as renewable energy sources (RES) and two fuel cells are used to compensate for sudden and unplanned changes in the production power of these two generators. The energy management unit manages the active and inactive state of the two fuel cells according to the production power and consumption power of the micro-grid in such a way that the power exchanged between the micro-grid and the main grid is limited within an acceptable range. The simulation results show that the proposed method using local continuous controllers (in each agent) and central discrete controller (energy management system) has been able to perform well and while providing the required power of the micro-grid, at the same time, it performs the current harmonics compensation issue correctly.
