Implementing consensus based distributed control in power system toolbox

This paper presents distributed control algorithm implementation in Power System Toolbox (PST). The distributed control algorithm is based on consensus and subgradient method. According this algorithm, each agent in a power system network can exchange information with their direct connected neighbors to unify all local marginal prices by consensus method. Synchronously, all agents update price information and power demands information to carry out economic operation based on subgradient method. The proposed method can realize economic dispatch and frequency regulation simultaneously. Power system toolbox (PST) is selected as the platform to implement the distributed control algorithm. The approach to implement this algorithm in PST is presented. Effect of the proposed algorithm is compared with a secondary frequency control via simulation results.
