摘要:

随着碳中和目标下分布式新能源发电的快速增长以及多能协同技术的不断成熟,多能源系统(MES)得到了快速发展,成为未来能源的主要承载形式。但MES包括生产、存储、消费等复杂环节,其经济运行面临挑战。在MES框架下构建了包含新能源发电站、电池储能装置和冷热电联供装置的经济优化模型,以弃风弃光惩罚成本、电池储能装置放电损耗成本、燃气轮机燃气成本、碳排放惩罚成本等最小为目标函数,以电池储能装置的充放电特性、光伏与风力发电机组的出力特性、冷热电平衡等为约束条件,采用一种新型的自适应学习率萤火虫算法(ALRFA)对优化模型进行求解,通过引入自适应学习率参数,可避免陷入局部最优、收敛速度慢等问题。以某园区的用户冷热电负荷为例,验证了所提模型和优化算法的有效性和可行性。

Abstract:

With the extensive application of renewable energy as power sources and the stepwise maturity of synergetic techniques, multi-energy system(MES) is drawing increasing attention,turning into the main carrier of energy on the way to achieving carbon neutrality. However, the economic operation of MES is confronting challenges due to the complexity of energy production, energy storage and energy consumption in the system. To tackle the problem, an economic optimization model of an MES including new energy power plants, a battery energy storage system(BESS) and a combined cooling heating and power(CCHP) system is formulated, taking minimizing the penalty of abandoning wind and solar power, power discharge loss of BESS, fuel costs of gas turbines, carbon emission penalty and other costs as the objective function. The optimization model is solved with the charging and discharging characteristics of BESS, the output characteristics of photovoltaic units and wind turbines and the balance between cooling, heating and electricity load as constraints. Afterward, a novel adaptive learning rate firefly algorithm(ALRFA) is proposed to prevent the problem solving from falling into local optimum and slow convergence by taking adaptive learning rate. Taking the cooling, heating and power loads of an industrial park as study case,the effectiveness and feasibility of the proposed model and algorithm is verified.
