摘　　要：园区综合能源系统可通过协调各类能源设备为用户提供可靠、优质、经济的能量供应,但源荷的不确定性和设备的变工况运行特性易导致较大的供/用能偏差。针对此问题,该文提出一种计及源荷不确定性与设备变工况特性的园区综合能源系统协同优化运行方法。首先,建立考虑多类型能量转换设备变工况运行特性的园区综合能源系统协同优化一体化模型,并利用非线性区间数表征源荷的不确定性;然后,利用区间可能度对非线性区间数进行确定性转换,并采用自适应分段线性化处理能量转换设备的变工况运行特性曲线;最后,以某园区综合能源系统为例进行仿真验证。仿真结果表明,所提方法能够有效地减小源荷不确定性与设备变工况特性带来的不利影响。The community integrated energy system can provide users with reliable,high-quality and economical energy supply by coordinating various energy equipment.However,the uncertainty of source and load and the off-design performance of equipment may easily lead to large energy supply/consumption deviation.To solve this problem,this paper proposes a collaborative optimal scheduling method considering source-load uncertainty and off-design performance.First,a collaborative optimization integrated model of community integrated energy system considering the off-design performance is established,and the uncertainty of source and load is represented by nonlinear interval number.Then,the nonlinear interval number is determinedly converted by using the interval possibility degree,and off-design performance curve is processed by adaptive piecewise linearization.Finally,an actual community integrated energy system is taken as an example for simulation verification.The simulation results show that the proposed method can effectively reduce the adverse effects of source-load uncertainty and off-design performance.
