冷热电联供微网环保经济调度研究
针对微网同时承担冷热电三种负荷的情况,提出了考虑蓄热蓄冷蓄电装置以及微源的冷热电联供微网环保经济调度模型。模型中设置冷热电供需实时平衡、微源及蓄能装置出力限制为约束条件,以微网运行的经济和环保的综合成本为目标函数。以一个包含燃气轮机、燃料电池、余热锅炉、吸收式制冷机、蓄电池、蓄热装置、蓄冷装置的微网为例,采用混沌粒子群优化算法对模型进行优化求解。算例验证了所提模型和算法的有效性,并讨论了不同蓄能装置对调度的影响。结果表明,蓄电池虽引起损耗上升,但能提高运行的经济性;蓄冷蓄热装置协调燃气轮机出力,降低了损耗和成本。...

| Bibliography: | In order to deal with the micro-grid with cold, heat and power demand, an environmental and economic dispatch model of combined cooling, heating and power micro-grid considering electricity storage, heat storage device, and cold storage device was proposed. With the real-time supply and demand balance of cold, heat and power and mi- cro sources and energy storage device output limits as constraints in the model, the total cost consisting of economy and environment cost of the micro-grid operation was the objective function. A micro-grld concluding gas turbine, fuel cell, waste heat boiler, absorption refrigerating machine, energy storage devices, was selected, which was solved by the algorithm of chaotic partial swarm. The algorithm example proves the validity of the proposed model and algorithm, and different effects that different kinds of energy storage devices have on the target are discussed. The results show that the battery has caused loss increase, but it can improve the economic operation, and coolin |
