    摘要:

    考虑区域综合能源系统运行时的经济性与低碳性,提出一种基于Q学习的区域综合能源系统低碳运行策略研究方法。首先,基于能量枢纽的概念构建区域综合能源系统的基本结构模型;接着,以计及二氧化碳治理费用的日运行费用最低为目标函数,提出区域综合能源系统的低碳经济运行策略;然后,针对低碳经济运行策略建立其马尔可夫决策问题,并采用改进的Q学习进行求解。通过仿真验证Q学习算法求解区域综合能源系统运行策略的有效性,结果表明,所提运行策略能充分发挥区域综合能源系统的多能互补优势,实现系统低碳经济运行,为区域综合能源系统的运行优化问题提供思路和策略。

    Abstract:

    Considering the economic and low-carbon performance of regional integrated energy systems, a method of low-carbon operation strategy of regional integrated energy systems based on the Q learning is proposed. Firstly, the basic operation model of such regional integrated energy system is constructed on the basis of the energy hub. Then, taking the minimum daily operating cost as the objective function, including the carbon dioxide treatment cost, a low-carbon economic operation strategy of regional integrated energy system is proposed. Then, the low-carbon economy operation strategy is modeled through the Markov decision problems, and the improved Q learning is utilized to solve thoseproblems. The simulation results verify the effectiveness of Q learning algorithm for solving operation strategies in the regional integrated energy system. It is shown that the proposed operation strategy can give full play to the multi-energy complementary advantage, and realize the economic and low-carbon objectives during operation of regional integrated energy system.
