摘要:

目的 为了提高电网新能源消纳能力、降低发电企业运营成本,解决大规模可再生能源馈入配电网时网损增大和新能源消纳率降低等问题,提出一种考虑数据中心(data center,DC)和储能协同调度的主动式配电网经济调度策略。 方法 首先,通过利用DC的时空可调特性,以及储能设备能够缓解电网发用电两侧矛盾的作用,充分协同调度DC和储能来达到削峰填谷;其次,为提高算法的搜索性能,在麻雀搜索算法中引入了Tent混沌初始化和多种群竞争等机制;然后,考虑到需求响应机制分时电价的影响,在储能成本、运行成本等多个约束条件下利用改进型麻雀搜索算法对模型进行优化调度,最大程度实现灵活性负荷与新能源的最优化匹配;最后,以改进IEEE 30和33节点系统为算例,仿真验证所提策略的有效性。 结果 提出的协同调度策略能够有效降低配电网综合运行成本,提高新能源消纳率。 结论 该策略可以为配电网经济调度的相关研究提供一定参考价值。

Abstract:

Objectives To improve the new energy consumption capacity of the power grid, reduce operational costs for power generation companies, and address issues such as increased network losses and reduced new energy consumption when large-scale renewable energy is integrated into the distribution networks, an economic scheduling strategy for active distribution networks with the inclusion of the coordinated scheduling of data center (DC) and energy storage is proposed. Methods Firstly, by utilizing the spatiotemporal adjustability of DC and the role of energy storage devices in alleviating the imbalance between grid supply and demand, the coordinated scheduling of DC and energy storage is fully leveraged to achieve peak shaving and valley filling. Secondly, the search performance of the sparrow search algorithm is improved by incorporating Tent Chaos initialization and multi-population competition mechanisms into the algorithm. Then, considering the impact of time-of-use pricing on the demand response mechanism, the model is optimized using an improved sparrow search algorithm under constraints such as energy storage costs and operational costs, aiming to achieve the optimal matching of flexible loads and new energy. Finally, the improved IEEE 30 and IEEE 33 node systems are taken as examples to verify the effectiveness of the proposed strategy. Results The proposed cooperative scheduling strategy can effectively reduce the overall operational costs of the distribution networks and improve the new energy consumption rate. Conclusions The strategy can provide some reference value for the related research of economic dispatch of distribution network.
