摘要/Abstract

摘要：

为降低含5G基站的多能工业园区供电成本,提出了一种多能工业园区全寿命周期供能系统规划方法。首先,建立了5G基站多能负荷模型并刻画了园区内多能流耦合特征;随后,以全寿命周期成本最低为目标函数,构建了工业园区供能系统规划模型;进一步,考虑园区内分布式光伏发电及多能负荷不确定性,并应用机会约束刻画不确定性对规划方案的影响,提升规划方案的鲁棒性。仿真算例表明,通过园区内多能互补,园区年用能成本降低0.52%、年规划投资成本降低7.6%,验证了所提方法的有效性。此外,通过调整模型机会约束越限概率参数,可有效平衡规划方案鲁棒性与经济性。

Abstract:

In order to reduce the power supply cost of the multi-energy industrial park with 5G base stations, this paper proposes a life-cycle energy supply system planning method for the multi-energy industrial park. Firstly, the multi-energy load model of 5G base station is established and the coupling characteristics of multi-energy flows in the park are described. Then, taking the lowest life cycle costs as the objective function, the planning model of the industrial park is constructed. Further, considering the uncertainty of distributed photovoltaic power generation and multi-energy loads in the park, and applying the chance constraints to describe the influence of uncertainty on the planning scheme, the robustness of the planning scheme is improved. The simulation examples shows that the annual energy cost of the park is reduced by 0.52 % and the annual planning investment cost is reduced by 7.6 % through multi-energy complementarity in the park, which verifies the effectiveness of the proposed method. In addition, the robustness and economy of the planning scheme can be effectively balanced by adjusting the over-limit probability parameters of chance constraints in the model.

Key words: 5G base station, multi-energy industrial park, chance-constrained programming, life cycle cost
