摘要

【目的】 在含新能源的源网荷储一体化系统中，为优化参与削峰辅助服务电动汽车用户和负荷聚合商收益，建立了考虑各时段削峰需求程度的电动汽车集群充放电策略优化模型，并优化了参与削峰后续时段电动汽车集群充放电策略。【方法】 首先，评估新能源出力场景下的各时段削峰需求；其次，基于各时段削峰需求程度，以负荷聚合商和电动汽车用户双方总期望收益最大为目标，建立电动汽车集群充放电策略优化模型；最后，为避免参与削峰服务后的电动汽车集群负荷出现负荷尖峰，以负荷波动最小为目标优化后续时段充放电策略。【结果】 算例分析表明，所提充放电策略可辅助平滑高峰期用电负荷，同时使负荷聚合商和电动汽车用户总期望收益最大化，并抑制了参与削峰服务后的“负荷尖峰”现象。【结论】 所提策略相较于不考虑参与削峰服务策略的电动汽车用户和负荷聚合商收益明显提高，削峰后续时段负荷波动明显降低，验证了所提方法的实用性和有效性。

Abstract

[Objective] In a source-grid-load-storage system incorporating renewable energy， an electric vehicle （EV） cluster charging and discharging strategy optimization model is established to optimize the revenues of EV users and load aggregators participating in peak-shaving ancillary services， considering the peak-shaving demand levels across different time periods.[Methods] First， the peak-shaving demand for each time period under renewable energy production scenarios was assessed. Second， based on the level of the peak-shaving demand in each time period， an optimization model for the charging and discharging strategy of the EV cluster was developed to maximize the total expected revenue for both load aggregators and EV users. Finally， to prevent peak load occurrences after participating in peak-shaving services， the charging and discharging strategy for subsequent time periods were optimized to minimize load fluctuations.[Results] The case analysis demonstrated that the proposed charging and discharging strategy assisted in smoothing the electricity load during peak periods， maximized the total expected revenue for load aggregators and EV users， and mitigated the occurrence of load peaks after participating in peak-shaving services.[Conclusions] The strategy proposed in this study significantly improved the benefits for EV users and load aggregators compared with the strategy without considering participation in the peak-shaving service， and the load fluctuations in the subsequent period of peak shaving were significantly reduced that verified the practicality and effectiveness of the proposed method.

摘要

With the large-scale development of distributed power supply, electric vehicles and other diversified new elements of the new industry, superimposed on the frequent occurrence of floods, typhoons and other extreme events, the distribution network planning, design and investment decision-making faces great challenges. However, the traditional distribution network planning has not fully mobilized the new elements and new industries to support the power system. The paper firstly combs through the research status quo of extreme event impact quantification methods, resilience planning, and investment strategy, and summarizes the existing investment effectiveness evaluation methods, and finally combines the distribution network development demands adapted to extreme events, and puts forward an outlook on the future research direction of resilience planning and investment strategy optimization.

The connection of large-scale renewable energy to the power grid reduces the frequency stability of the power system, which brings new problems and challenges to the secondary frequency regulation of the power system. With a large cluster, the electric vehicles have become a new type of frequency-regulation resources due to its accurate and fast dynamic response capability. This paper first summarizes the system framework of numerous electric vehicles participating in frequency-regulation ancillary service and introduces two methods to quantify the adjustable capacity of aggregated electric vehicles. One method quantifies the adjustable capacity of the aggregated electric vehicles directly, and another one presents the energy feasible region of the aggregated electric vehicles. Then, the day-ahead optimal scheduling and the real-time control process of electric vehicles participating in secondary frequency regulation of the power system are reviewed from different aspects: model, method, and application. Finally, the future research direction and key technologies of numerous electric vehicles participating in secondary frequency regulation of the power system are prospected.
