Transmission Congestion Management Based on MultiAgent Theory

The congestion mitigation scheme based on the multi-agent model has more flexibility than the traditional LP method. It provides market participants with additional freedom to make reasonable adjustments. Market participants are allowed not only to make decremental adjustments based on LP but also allowed to make increments based on their impact on the transmission line just as green agents did at the second stage. In this proposed agent method, market participants should make a choice between accepting congestion charges and offering voluntary adjustments at their own costs. Once the congestion occurs, participants who have physically utilized the congested lines will have to bear the related economic losses. Although congestion loss or revenue due to limited adjustment ranges may be minute, they may be substantial based on the submitted IPS. The general goal is to mitigate the congestion effectively, so the agent with the bigger distribution factor and lower price will be adjusted initially.
