    摘要:

    随着风电等清洁能源接入电网比例不断升高,系统调峰压力逐渐提升。为促进风电消纳,提出一种考虑含储热的热电联产(CHP)机组与火电深调相结合的源荷侧联合优化调峰方法。在源侧,CHP机组加装储热装置,结合火电机组深度调峰技术,为风电消纳提供空间;在荷侧,考虑用户侧响应,通过动态分时电价引导用户主动优化用电曲线,改善风电反调峰现象。联合优化模型以系统总运行调度成本最小为目标,综合考虑源侧储热约束、火电机组寿命损失成本及荷侧用户响应满意度约束等。算例结果表明该模型能够在保证用户用电满意度的同时,以最低的调度运行成本最大化优化系统调峰效果,有效减少新能源弃电。

    Abstract:

    Wind power and other clean energy sources are continuously increasing their share in the grid, posing significant challenges to peak load regulation. To promote the integration of wind power, a source?load side joint optimization peak regulation method is proposed, which combines heat and power generation (CHP) units including heat storage capabilities with deep adjustments in thermal power generation. On the source side, CHP units are equipped with thermal storage devices, combined with deep peak regulation technology from thermal power units, to increase the capacity for wind power integration. On the load side, considering user response, users are guided to proactively optimize their electricity consumption curves through dynamic time?of?use pricing, improving the phenomenon of wind power anti?peak regulation. The joint optimization model aims to minimize the overall operational scheduling cost of the system, taking into account source?side thermal storage constraints, thermal power unit lifespan loss costs, and load?side user response satisfaction constraints. Calculation example results demonstrate that this model is capable of maximizing the optimization of system peak regulation while ensuring user satisfaction with electricity consumption and minimizing scheduling operational costs, effectively reducing the curtailment of new energy sources.
