Low-carbon optimal dispatch strategy for multi-energy systems taking into account source-load stochasticity
Aiming at the problem of wind power and load stochasticity affecting the stability of multi-energy system dispatch,a low-car-bon optimal dispatch strategy for multi-energy system taking into account the source-load stochasticity was investigated by using a linear-ization method.Considering the wind power fluctuation,the stochastic behavior of market electricity price and the elasticity coefficient of autonomous adjustment of electric load,the domain of wind power and electric load fluctuation was constructed;using the linearization process of a sorted truncation apportionment method,the domain of wind power and electric load fluctuation was linearized,so that the o-riginal uncertain optimization problem was transformed into a deterministic optimization problem,which was easy to be solved directly;the framework of low-carbon optimization of multi-energy system considering the linearization of wind power and electric load was con-structed,and the impact of a tiered carbon pricing mechanism on wind power consumption and carbon emissions was further analyzed.The example analysis shows that the linearization process of the sorted truncation apportionment method can be directly applied to the deterministic optimization problem and simplify the solution process.The carbon trading price analyzed based on the above method is reasonable and effective in the context of current energy prices,and can promote the synergy of economy and low-carbon of multi-energy systems.
