摘　　要：为了实现园区综合能源系统(PIES)的低碳化经济运行和多能源互补,解决碳捕集装置耗电与捕碳需求之间的矛盾,以及不确定性源荷实时响应的问题,提出了基于近端策略优化算法含碳捕集的综合能源系统低碳经济调度方法。该方法通过在PIES中添加碳捕集装置,解决了碳捕集装置耗电和捕碳需求之间的矛盾,进而实现了PIES的低碳化运行;通过采用近端策略优化算法对PIES进行动态调度,解决了源荷的不确定性,平衡了各种能源的供给需求,进而降低了系统的运行成本。实验结果表明:该方法实现了不确定性源荷的实时响应,并相比于DDPG(deep deterministic policy gradient)和DQN(deep Q network)方法在低碳化经济运行方面具有有效性及先进性。In order to achieve low-carbon economic operation and multi energy complementarity of the PIES in the park,solve the contradiction between power consumption and carbon capture demand of carbon capture devices,as well as the problem of real-time response to uncertain source loads,this paper proposed a low-carbon economic scheduling method for the comprehensive energy system with carbon capture based on proximal strategy optimization algorithm.This method solved the contradiction between power consumption and carbon capture demand of carbon capture devices by adding carbon capture devices to PIES,thereby achieving low-carbon operation of PIES.By adopting a proximal strategy optimization algorithm for dynamic scheduling of PIES,it solved the uncertainty of source and load,and balanced the supply and demand of various energy sources,thereby reducing the operating cost of the system.The experimental results show that this method realizes the real-time response of uncertain source loads,and is effective and progressiveness in low-carbon economic operation compared with DDPG and DQN methods.
