摘要:

目的 在实现“双碳”目标的过程中,虚拟电厂作为新型能源管理系统,能够提升电网灵活性和能源效率。但电转气(power to gas,P2G)、碳捕集系统(carbon capture system,CCS)耦合失效,能量利用率低,可再生能源波动性高,以及减排政策激励不足等问题影响了虚拟电厂的经济性,为此,基于储液式CCS和燃气掺氢设备提出一种兼顾低碳性和经济性的优化调度模型。 方法 从新型低碳设备和碳交易政策2个角度出发,首先建立了储液式碳捕集耦合电转气设备、燃气轮机、电热炉以及储能设备等的数学模型;其次,针对不同碳排量设计了阶梯式碳交易价格,并引入价格补偿因子和价格增长因子来激励虚拟电厂减排,提出了以经济性和低碳性为目标函数的优化调度策略;最后,使用线性化方法处理了模型以便高效求解。算例分析设置了不同掺氢比场景、不同耦合设备场景,以及不同碳交易机制场景以验证所提模型的有效性。 结果 与改动之前的虚拟电厂相比,变掺氢运行和储液式P2G-CCS耦合设备分别使得运行成本降低了6.21%、12.62%,阶梯式碳交易价格使得虚拟电厂碳排量减少了12.96%。 结论 该调度模型可以有效实现低碳排放,提升风电的消纳能力以及降低虚拟电厂的运行成本。

Abstract:

Objectives In the process of achieving the “dual carbon” goals, virtual power plants, as a new energy management system, can enhance the flexibility and energy efficiency of the power grid. Issues such as the failure of coupling between power-to-gas (P2G) and carbon capture system (CCS), low energy utilization efficiency, high volatility of renewable energy, and insufficient incentives from emission reduction policies have affected the economic viability of virtual power plants. Therefore, an optimized scheduling model that balances low-carbon and economic considerations is proposed based on liquid storage CCS and gas hydrogen blending equipment. Methods From the two perspectives of innovative low-carbon equipment and carbon trading policy, mathematical models are first established for the liquid-storage carbon capture system coupled with power-to-gas equipment, gas turbines, electric heating furnaces, and energy storage equipment. Secondly, tiered carbon trading prices are designed for different carbon emission levels, and price compensation factors and price growth factors are introduced to incentivize virtual power plants to reduce emissions. Optimized scheduling strategies with economic and low-carbon objectives as the target functions are proposed. Finally, the model is processed using a linearization method for efficient solution. Case analysis sets different hydrogen blending ratio scenarios, different coupled equipment scenarios, and different carbon trading mechanism scenarios to validate the effectiveness of the proposed model. Results Compared with the virtual power plant before modification, variable hydrogen blending operation and the liquid-storage P2G-CCS coupling equipment reduce operating costs by 6.21% and 12.62%, respectively, and the tiered carbon trading price reduces carbon emissions of the virtual power plant by 12.96%. Conclusions The proposed scheduling model can effectively achieve low-carbon emissions, enhance wind power integration capability, and reduce operating costs of virtual power plants.
