A multi-agent based distributed reactive power control method

This paper introduced a new concept to improve the traditional control of voltage and reactive power. The proposed system divides the traditional problem of this control into two sub problems, ldquovoltage controlrdquo to adjust a substation´s secondary bus voltage and ldquoreactive power controlrdquo to adjust a substation´s primary bus voltage. This paper presented the ldquoreactive power controlrdquo aspect of this new method. In order to verify the performance of the proposed method, it has been applied to the model network system. Its results confirm that our proposed method is able to control very violent fluctuations in load. The three kinds of agents employed performed their respective roles well, adjusting the reactive power among the different substations and keeping the primary bus voltage in the correct range.
