Optimization strategy of multi-type energy storage considering carbon constraints

Aiming at the problem of difficult carbon and electricity coupling and new energy consumption in the new power system, this paper proposes a multiple energy storage optimization operation model considering carbon constraints. Firstly, a mathematical model is established according to the response characteristics of each energy storage, and the corresponding constraints are set; secondly, a carbon trading mechanism for an integrated energy system is constructed by considering the actual carbon emission of a gas turbine; finally, the linear programming problem is solved by a solver with the objective function of minimising the sum of the carbon trading cost and the operation and maintenance cost. The results show that the reasonable allocation of the proportion of each energy storage is conducive to improving the system operation economy, and the carbon emissions are significantly reduced after the introduction of the carbon trading mechanism.
