Load following under different market models in a restructured power system

Abstract

Load following is one of the major components which ensures the secured operation of power systems. The complexity of the load following control strategy increases when the system operates under deregulated environment. A load following system has to control not only the frequency and tie line power but also the power generation as per the contract. The contract is decided by any one of the three market model namely single buyer, bilateral and poolco model. This paper develops load following system operating under different models. The generalized factors based on which the load following satisfies the scheduled and violated power are computed for all market models. Finally the system is simulated under different models with contract violation to justify the performance of load follower. The developed generalized market participation factors and violation participation factors make the load follower to yield desired secured power system.
