| 大规模发展可再生能源是构建低碳可持续能源系统的重要保障，源-荷协同调峰是消纳可再生能源的有效途径。为此，研究含光伏的油田综合能源系统的热电厂和需求响应协同调峰，分析冬季典型场景下的热电厂热电耦合机理，建立热电耦合调峰约束；针对油田综合负荷的用能特性和分布式光伏发电的特点，建立负荷集群的用电数学模型和用热数学模型，考虑热电机组、负荷响应及源-荷系统运行技术约束，以油田全局能耗成本最小为目标建立自备热电厂和需求响应协同调峰优化模型，制定油田电网源-荷协同调峰策略，通过循环寻优求解源-荷协同最大调峰能力。算例分析表明，源-荷协同光伏发电调峰能有效地提高油田电网对光伏发电的消纳能力，供暖负荷的需求响应使冬季热电厂“以热定电”的刚性约束弹性化，调峰贡献度在需求响应中占比最大。 |

| Abstract: |
| The large-scale development of renewable energy is an important guarantee for the construction of low-carbon sustainable energy system, and the source-load coordinated peak load regulation is an effective way to absorb renewable energy. For that, the cooperative peak load regulation of thermal power plant and demand response for oil field integrated energy system with photovoltaic is studied. The thermoelectric coupling mechanism of thermal power plant in typical winter scenario is analyzed, and the thermoelectric coupling peak load regulation constraint is established. As for the energy consumption characteristics of oil field comprehensive load and features of distributed photovoltaic power generation, the mathematical models of power consumption and heat utilization of load cluster are established. Considering the technical constraints of thermoelectric units, load response and source-load system operation, the collaborative peak load regulation optimal model of self-provided thermal power plant and demand response is established with the objective of minimizing the overall energy consumption cost of oil field, and the collaborative peak load regulation strategy for oil field power grid is formulated. The maximum peak load regulation ability of source-load coordination is solved by cycle optimization. The case analysis shows that the cooperative peak load regulation of source, load and photovoltaic power generation can effectively improve the absorption ability of oil field power grid for photovoltaic power generation. The demand response of heating load makes the rigid constraint of thermal power plant “power determined by heat” in winter flexible, and the peak load regulation contribution accounts for the largest proportion in the demand response. |
