计及碳配额的混合储能综合微能源网优化运行研究

当前综合微能源网系统优化运行策略鲜少考虑碳交易政策影响，为此，文中提出一种计及碳排放成本的混合储能综合微能源网系统优化运行模型。该模型首先结合源-荷-储及能源转换装置进行综合微能源网系统配置，根据碳排放配额分配实施方案建立考虑碳配额的优化目标函数。然后以某地区数据为算例基础进行仿真，利用Gurobi求解得到满足碳排放成本最小时的系统优化运行结果。算例结果表明，碳排放免费配额能够降低综合微能源网系统运行成本，影响系统运行策略。文中所提模型能够反映碳排放成本因素对能源消费结构的影响，为综合微能源网系统能源结构配置与运行提供参考和依据。

Optimal operation of hybrid energy storage integrated micro-energy network considering carbon quote

The integrated micro-energy grid system is constructed using multiple energy sources such as electricity, heat, cooling and gas, and can be a small-scale renewable energy supply system that can supply multiple types of energy. However, due to the randomness and volatility of renewable energy sources such as photovoltaics and wind power, when the load fluctuates, this system may cause the system to collapse. At the same time, the domestic carbon emissions trading market has been launched, and the cost of carbon emissions in the integrated energy system cannot be ignored. To this end, this paper proposes a hybrid energy storage micro-energy grid optimized operation model that takes into account the cost of carbon emissions. The model firstly combines source-load-storage and energy conversion devices to configure a comprehensive micro-energy grid, and then establishes an objective optimization function considering carbon allowances according to the carbon emission allowance allocation implementation plan, next it simulated based on data from three typical daily scenarios in a certain area, and finally uses Gurobi to solve the system optimization operation results that meet the minimum cost of carbon emissions. The results of the calculation examples show that the free carbon emission allowance can reduce the operating cost of the integrated energy system and affect the system operation strategy, and the model proposed in this paper can reflect the impact of carbon emission cost factors on the energy consumption structure, verifying that energy storage devices can improve the economy, safety and reliability of the integrated micro-energy grid system, and configure the energy structure of the integrated energy system. Provide reference and basis for operation.
