| 摘要: |
| 电转气设备的应用可实现能源转换，大力消纳可再生能源。电转气设备与燃气轮机的结合，可使能量在电网和天然气系统中双向流动。提出一种配置电转气设备的电-气联合系统优化模型，分析电转气设备的应用对负荷供能率及可再生能源过剩率的影响。介绍了电转气设备的应用场景及联合系统配置模型；设置了相应指标对联合系统进行建模，并以电转气设备、蓄电池和燃气轮机的建设及运维成本最小为目标函数。算例结果表明，电转气技术提升了负荷供能率，降低了弃风水平。 |

| Abstract: |
| P2G(Power to Gas) facility can be applied to realize the energy conversion for the accommodation of massive renewable energy and the combination of P2G facility and gas turbine makes the bidirectional energy flow between power grid and natural gas network possible. An optimization model is proposed for the electricity-gas combination system with P2G planning and the impacts of P2G application on the energy acceptance rate of loads and the excess rate of renewable energy are analyzed. The P2G application cases and the combination system optimization model are introduced, the corresponding indexes for system modelling are set, and the minimum total cost of construction and maintenance for P2G facility, battery and gas turbine is taken as the objective. Results of case study show that, P2G technology improves the rate of energy-supply to loads and reduces the level of wind-power curtailment. |
