Considering the combined heat and power synergy of advanced adiabatic compressed air energy storage system in multi-objective optimal scheduling of virtual power plant
Addressing the deficiencies in existing virtual power plants regarding coordinated heat-power dispatch
which lead to high operational costs and carbon emissions
this paper proposes a coordinated heat-power dispatch model for virtual power plants incorporating an advanced adiabatic compressed air energy storage (AA-CAES) system. By exploring the closed-loop coupling characteristics of "energy storage–heat production–heat utilization
" the model aims to reduce system operational costs and carbon emissions. The model takes photovoltaic systems
wind turbines
micro gas turbines
batteries
thermal storage tanks
and AA-CAES as core components
establishing an electricity-heat-gas multi-energy flow coordination framework. It elaborately characterizes the interactive constraints between heat recovery and heat release demand during the compression energy storage process and adopts the minimization of total operational cost and carbon emissions as dual objectives. Using typical daily data from an industrial park in Qinghai Province as a case study
comparative scenarios with and without AA-CAES are established. The augmented ε-constraint method combined with the entropy-weighted TOPSIS sequential decision-making algorithm is employed to derive the dual-optimal solutions for total cost and carbon emissions in VPP models with and without AA-CAES
respectively
for comparison. The results indicate that after configuring AA-CAES
the optimal compromise solution achieves a 5.1% reduction in total cost and a 5.0% optimization in electricity purchase cost
while carbon emissions decrease by 15.8%. Nighttime curtailed wind power is fully absorbed
and the share of gas turbine peak heating load decreases significantly
achieving a synergistic improvement in both economic efficiency and low-carbon performance. This provides theoretical and engineering references for the efficient and low-carbon dispatch of industrial virtual power plants in Qinghai.
