摘要：针对多能源电力系统中热电和风电的协调问题，从热电联合系统运营商的角度，深度挖掘热能和电能的互补特性，量化分析热电横向协调优化产生的主动能力，贯穿于整个纵向功率平衡过程中，从而与不确定性的风电统一参与电力市场，制定合理的运行策略，增强系统的可调度性与可控制性。首先，在分析运行策略影响因素的基础上，利用储热装置解耦载荷之间的耦合牵制，以总运行收益最大为目标，建立包含风电的热电联合系统调度模型，优化热电机组和储热装置的输出功率；进一步地，考虑风电预测偏差、储热装置运行灵活性及市场环境下的分时电价对系统运行策略的影响，并以储热装置容量为例，探究储热装置运行灵活性的制约因素；最后，在Visual Studio软件中，通过算例仿真验证所提模型的有效性与合理性。
Abstract:In view of the coordination of thermal power with wind power in multi energy power system, from the perspective of the combined thermoelectric power system operator, the complementary characteristics of thermal energy and electric energy were deeply explored, and the active capacity generated by the horizontal coordination and optimization of thermal power was quantitatively analyzed, which runs through the whole vertical power balance process so as to participate in the electricity market with uncertain wind power and formulate reasonable operation strategies, and enhance the schedule ability and controllability of the system. Firstly, on the basis of analyzing influencing factors of the operation strategy the coupling drag among heat loads was decoupled by heat storage devices, and taking the maximized total operation earning as the objective a dispatching model for combined heat and power system including wind power was established to optimize the output power of thermoelectric generating units and heat storage devices. Secondly, considering the impacts of predicted deviation of wind power, the operating flexibility of heat-storage devices and the time-of-use price under market environment on system operation strategy, taking the capacity of heat-storage for example, the factors restricting the operation flexibility of heat-storage devices were explored. Finally, the validity and rationality of the proposed model are verified by the computing example in the environment of Visual Studio software.
