摘要

综合能源系统（IES）机组的变工况特性导致求解结果存在误差。提出一种考虑机组变工况特性与碳-绿证交易机制的IES低碳经济运行方法。基于能量枢纽（EH）模型,构建考虑机组变工况特性的混合能源枢纽（HEH）模型,描述IES的多能耦合关系,提高不同工况下IES的建模精度。引入碳-绿证交易机制,有效耦合碳市场与绿证市场。同时,考虑经济性与低碳性,以系统总运行成本最小为目标函数,通过算例仿真验证该文构建模型的有效性。相较于仅考虑变工况特性方案,该文所提碳-绿证交易机制下,系统总运行成本降低了11.87%,有效实现了综合能源系统经济运行。

Abstract

The off-design characteristics of units in integrated energy systems （IES） leads to errors in the solution results. A low-carbon economic operation method of IES is proposed, which combines off-design characteristics of units and a ladder carbon-green certificate trading mechanism. Based on an energy hub （EH） model, a hybrid energy hub （HEH） model considering off-design characteristics of units is established to describe multi-energy coupling relationships of the IES and enhance the modeling precision of IES during different working conditions. A ladder carbon-green certificate trading mechanism is introduced to effectively couple the carbon and the green certificate market. Meanwhile, the objective function of IES is proposed by minimizing total operation cost considering the economy and low carbon emissions, and numerous simulations verify the effectiveness of the proposed model. Compared with only considering off-design characteristics of units, the total operation cost of proposed system in this paper is retuced by 11.87% under the ladder carbon-green certificate trading mechanism proposed in this paper, which can realize the economic operation of IES.
