ABSTRACT:
This paper
presents the modeling of intelligent energy control center (ECC) controlling
distributed generators (DGs) using multi-agent system. Multi-agent system has
been proposed to provide intelligent energy control and management in grids
because of their benefits of extensibility, autonomy, reduced maintenance, etc.
The multi-agent system constituting the smart grid and agents such as user
agent, control agent, database agent, distributed energy resources (DER) agent
work in collaboration to perform assigned tasks. The wind power generator
connected with local load, the solar power connected with local load and the ECC
controlled by fuzzy logic controller (FLC) are simulated in MATLAB/SIMULINK.
The DER model is created in client and ECC is created in server. Communication
between the server and the client is established using transmission control
protocol/internet protocol (TCP/IP). The results indicate that the controlling of
DER agent can be achieved both from server and client.

0.1 s and circuit breaker (CB-2) closed after 0.3 s to interconnect solar power to wind observed up to 0.6 s.
CONCLUSION:
The simulation model of ECC, controlling
the solar power generation and wind power generation interconnected with grid using
multi-agent system is described in this paper. The voltage of wind and solar
power are stored in a excel sheet as a database agent. Intelligent controller FLC
controls the switch provided in the solar panel to add/remove depending upon
the voltage requirements. This excel sheet acting as a monitoring tool to access
the simulation results, provides the visualization of the grid. The results
prove that the multi-agent component controls the Distributed Energy Resources.
