Design and Clearing Optimization of Inter-provincial and Intra-provincial Two-level Market Transaction Mode Under New Power System
In order to achieve the goal of"carbon peaking and carbon neutrality",General Secretary Xi Jinping pro-posed to build a power system with new energy as the main body.It is one of the important ways to realize the goal of"double carbon"to establish a new power system market trading mode for low-carbon energy transition.Therefore,a two-level inter-provincial-intra-provincial market transaction model and a clearing optimization model were proposed.First,the pa-per analyzed the characteristics of high proportion of clean en-ergy access,high proportion of cross-regional power transmis-sion and high proportion of flexible resource regulation under the new power system and described its market trading frame-work.Secondly,the provincial market transaction with new en-ergy as the main body was designed,including annual bilateral negotiation/centralized bidding transaction,monthly bilateral negotiation/centralized bidding transaction,monthly(multi-day)transaction and auxiliary service transaction.Inter-provin-cial transaction mode was designed,including annual/monthly inter-provincial and inter-regional transaction,inter-provincial electricity purchase transaction,clean energy delivery transac-tion and inter-provincial peak regulation auxiliary service trans-action.On the basis that the balance between supply and de-mand of electricity is satisfied,the day-ahead market clearing model aiming at the maximum consumption of clean energy in the province and the day-ahead market clearing model aiming at the minimum total cost were constructed.Finally,a new power system in a province was taken as an example to simu-late day-ahead and day-day market trading under typical scen-arios.The results show that the proposed market trading mode effectively promotes the consumption of clean energy,slows down the occurrence of wind and light abandonment,power ra-tioning and other phenomena,and promotes the realization of the"double carbon"goal.
