INTRODUCTION • The increasing demand on the power grid.

• Infeasibility of large central generation units due to the high cost and the losses in the transmission.

• The high penetration of distributed generation.

• The rapid expansion, the complexity of control…

Smart Grid• Microgrid: is a localized grouping of distributed energy resources and controllable interconnected load all connected to the grid through single point of common coupling.

• Decentralized Control.

• Multi Agent Systems: is a representation of an intelligent society of agents with goals and behaviors to interact with the environment and the other agents.

TESTING AND RESULTS

• This scenario mimics the normal daily load profile in the selected area.

• First the demand starts at 1.9 MW.

• Then it increases to reach the peak at 2.6 MW.

• After that it goes down again to 1.9 MW.

• The agent is given 2.18 MW as a limitation power.

TESTING AND RESULTS

• This scenario tests the agent ability to control the two controllable PV units when the load is very low.

• First the load start at 1.7 MW.

• Then it drops to 1.3 MW.

• After that the load goes down to 1 MW.

• And Finally it experience a further decrease to 309 KW.

DISCUSSION The designed system runs smoothly in the normal operation condition satisfying the power quality standards (voltage level, frequency, and harmonic distortion).

Agent was able to perform its function and provide real time response signals through the TCP/IP connection.

The Agent operation on the load and the PV units doesn’t affect the system stability, indicated from the stable voltage level and frequency.

Priority algorithm can be unfair for the load with the lowest priority.

Controlling the PV units was based on the needed demand and doesn’t consider the generation optimization or the economical dispatch.

FUTURE WORK Improving the Microgrid modeling by include more design details like the lines impedance from the feeder and to simulate the daily irradiance and temperature variance in the selected zone.

Exploiting the potential of the Multi Agent System by designing agents with dedicated goal to contribute in the decision making, as to introduce agents for the generation optimization.

Implementing the proposed structure for small house scale control where the priority algorithm can be more suitable in controlling the house appliances, which will enable demand side response.
