A Bi-layer Capacity Planning Method for Park Integrated Energy System Considering Exhaust Gas Emission Penalties

In order to ensure the stability and guarantee the economic and environmental friendliness of park integrated energy system (PIES), a bi-layer capacity planning method for PIES considering exhaust gas emission penalties is proposed. In the outer layer of planning, the emphasis is placed on minimizing the construction cost, energy purchase cost and renewable energy curtailment cost of PIES. The inner layer of planning sets the operation cost and exhaust gas emission penalties of PIES as the objective function and introduces a penalty mechanism to incentivize proactive management and reduce waste gas emissions. By integrating considerations of environmental protection and economy of PIES, this bi-layer planning approach provides a comprehensive and effective solution for the sustainable development of PIES. Through the application of real-world case studies, the method has been validated to not only enhance energy efficiency but also significantly improve environmental quality, demonstrating its practical significance and potential for wider adoption.
