“…Furthermore, to verify the validity of the generated codes and to evaluate the effect of the reduction of coding work of the proposed method and supporting tools, we have developed agent-based microgrid control system [13] [14] which had been designed and implemented before. The comparison between the developing process with and without the proposed mehtod Microgrid is a distributed power system composed with different kind of power units and each unit has been controlled by a software agent which communicate with each other using cooperation protocol.…”

This paper proposed a repository-based methodology of cooperation protocol design for multi-agent system (MAS). Software reuse is the essential of software engineering and also important to MAS development. Based on the repository, proposed methodology gives the guideline for fully reuse the existing codes and creating new protocol template to extent protocol library. Furthermore, a graphical design tool has been created to support the proposal and the code generation function actually reduced the coding burdens.

“…Microgrid is a small-scale power system that consists of distributed generators, power storage equipment and customers, and has the connection at one point to the grid. Microgrid performs supply and demand adjustment to control the battery or distributed power sources in response to changes in load demand, and serves as a good citizen for the grid [4][5][6][7][8][9][10][11].…”

In this paper, we propose an autonomous microgrid operation by using multi-agent approach. The proposed multi-agent system consists of seven types of agent (AG). In a microgrid, load AGs act as consumers or buyers, generator AGs, photovoltaic AGs and wind-turbine generation AGs act as producers or sellers, and battery AGs act as prosumers or sellers/buyers. In order to verify the performance of the proposed system, it applied to a simple model system with different electrical power prices. From the simulation results, it can be seen the proposed multi-agent system could perform a smart-grid operation efficiently.

“…The microgrid also offers economical opportunities by introducing combined heat and power (CHP) units, which are currently the most important means of improving energy efficiency [5,6]. This system is interconnected to the distribution network of the utility, but they can also be operated in isolated mode from the main grid in the case of faults in the upstream network [7][8][9][10]. In grid-connected mode, the frequency and voltage of the microgrid is maintained within a tight range by the main grid.…”

Abstract:Recently, interest in microgrids, which are composed of distributed generation (DG), distributed storage (DS), and loads, has been growing as a potentially effective clean energy system to mitigate against climate change. The microgrid is operated in the grid-connected mode and the islanded mode according to the conditions of the upstream power grid. The role of the energy storage system (ESS) is especially important to maintain constant the frequency and voltage of an islanded microgrid. For this reason, various approaches for ESS control have been put forth. In this paper, a fuzzy PID controller is proposed to improve the frequency control performance of the ESS. This fuzzy PID controller consists of a fuzzy logic controller and a conventional PI controller, connected in series. The fuzzy logic controller has two input signals, and then the output signal of the fuzzy logic controller is the input signal of the conventional PI controller. For comparison of control performance, gains of each PI controller and fuzzy PID controller are tuned by the particle swam optimization (PSO) algorithm. In the simulation study, the control performance of the fuzzy PID was also tested under various operating conditions using the PSCAD/EMTDC simulation platform.
