为充分利用工业蒸汽发电机的灵活性，首次提出面向工业蒸汽发电机的虚拟储能方案。该方案将储能系统与工业蒸汽发电机结合构建虚拟储能系统，利用储能的快速功率调节能力补偿工业蒸汽发电机升降功率过程中的爬坡，提出虚拟储能方案下储能系统的容量配置方法，根据发电机功率最大上调过程所需功率和能量设计储能系统容量。其次，提出虚拟储能内部功率控制策略，在内部发电机升降功率过程中按照灵活性服务需求来控制储能充放电。最后，通过算例验证所提虚拟储能系统配置方案的有效性和经济性。敏感性分析结果表明，灵活性市场价格的变化对虚拟储能系统配置方案的推广影响较小，储能的技术进步和成本降低更有助于其未来应用。
Abstract：To fully utilize the flexibility within industrial steam power generators,a virtual energy storage scheme tailored for industrial steam power generators is proposed for the first time. Under this scheme,an energy storage system is integrated with industrial steam power generators to construct a virtual energy storage system(VESS),leveraging the fast power regulation capability of energy storage to compensate for the ramp-up during the upward and downward processes of industrial steam generators. Furthermore,a capacity configuration method for the energy storage system under the virtual energy storage scheme is provided,which designs the capacity of the energy storage system according to the required power and energy during the upward process of the generator towards the maximum generation power. In addition,an internal power control strategy for virtual energy storage is put forward,under which the charging and discharging of energy storage is controlled to meet the flexibility service requirements during the upward and downward processes of the internal generator. Finally,a case study is used to validate the effectiveness and economy of the proposed VESS scheme. The results of sensitivity analysis indicate that the impact of variations in the flexibility market price on the promotion of the VESS scheme is minor,while the technical advancement and cost reduction of energy storage are more beneficial for its applications in the future.
