摘要
在传统的利用内燃机驱动的冷热电联供系统的基础上,研究提出了一种结合可再生能源发电和内燃机联合驱动的新型冷热电联供系统模型,并加入储能装置提高可再生能源的利用率去克服可再生能源不稳定性。然后建立以冷热电联供系统的经济性、一次能源消耗量和系统的节能率为模型的冷热电联供系统,以系统的燃料成本、与主网能量的交互成本和排放污染气体所产生的环境成本为优化变量,采用空间粒子群算法进行求解。仿真结果表明,相比传统冷热电联供系统,研究所提的CCHP系统模型能够有效促进能源的高效利用,达到节能减排的目的。
Based on the traditional combined cooling heating and power(CCHP)system driven by internal combustion engine,the research proposes a new CCHP system model combined with renewable energy power generation and internal combustion engine,and adds energy storage device to improve the utilization of renewable energy Rate to overcome the instability of renewable energy.Then,a combined heat and power system based on the economy of the CCHP system,the primary energy consumption and the energy saving rate of the system is set up.The cost of the system,the interaction cost of the system with the energy of the main network,and the emission of polluting gas The resulting environmental costs are optimization variables and are solved using a SC-PSO(Space-Coupling PSO)algorithm.The simulation results show that compared with the traditional CCHP system,the proposed CCHP system model can effectively promote the efficient use of energy and achieve the goal of energy conservation and emission reduction.
