Peak Regulation Right Transaction Considering Energy Saving and Emission Reduction
The generation capacity of power system is surplus during non-peak period,making the units work away from economic operation points.A large number of primary energy is consumed and thus environmental pollution is caused during unit commitment of some generating units with weaker peak regulation capacity.With reference to peak regualtion right trading mechanism of buying peak regulation capacity,this paper presents a weighted algorithm for environment costs during peak shaving with regard to the energy consuption during unit commitment.In the case study of the generating unit field measured energy consumption and environment cost in the power plants within East China Power Grid,the social effects of energy saving and emission reduction are compared before and after peak regulation right transaction.It is verified that peak shaving trading has the effect of saving energy and reducing consumption by avoiding frequent unit commitment,but without any increase of peak shaving unit capacity.
