| 摘要: |
| 随着多市场主体接入，如何管理系统中的分布式资源成为气电区域综合能源系统的核心问题。从激励价格角度出发，建立含商业楼宇和分布式电源2类市场主体的区域综合能源系统日前市场出清模型，综合考虑节点净有功负荷、净无功负荷和天然气负荷对系统运行的影响，通过引入多类灵敏度因子线性化潮流约束和稳态气流约束；进一步地，将出清的节点边际价格分为有功基础电价、无功基础电价、阻塞管理电价、电压支撑电价、网损边际电价、基础气价和气压支撑价格7类，通过不同价格信号引导促使市场主体调节自身运行方式支撑系统运行。基于改进的IEEE 33节点配电网和24节点气网构成的区域综合能源系统的仿真结果验证了所提出的基于节点边际价格分解的定价策略的有效性和合理性。 |

| Abstract: |
| With the access of multiple market entities, how to manage distributed resources in the system becomes a key problem of gas-electricity integrated energy system. From the perspective of incentive price, a day-ahead market clearing model for integrated energy system with two types of market entities including commercial building and distributed generators is established. The influence of net active power load, net reactive power load and natural gas load on system operation is considered comprehensively, and multiple sensitivity factors are introduced to linearize power flow and steady-state gas flow constraints. Further, the cleared distribution locational marginal price is divided into seven categories, i. e.,baseline active power price, baseline reactive power price, congestion management price, voltage support price, network loss price, baseline gas price and node pressure support price. Each market entity is encouraged to adjust its own operation mode to support system operation through the guidance of different price signals. Simulative results based on the integrated energy system composed by modified IEEE 33-bus distribution network and 24-node gas network verify the effectiveness and rationality of the proposed pricing strategy based on locational marginal price decomposition. |
