摘　　要：随着以电动汽车、温控负荷和分布式储能为代表的柔性负荷在新一代智能电网接入的比例不断增加,柔性负荷聚合商将作为投标主体参与到日前电力市场的投标竞价中。该文提出计及不确定性的柔性负荷聚合商参与日前市场的随机-鲁棒联合投标决策模型,以柔性负荷聚合商投标支出最小化为目标,采用随机场景模拟电价的不确定性,利用可调鲁棒控制系数处理电动汽车充电行为及温控负荷中外界温度变化的随机性,使用响应意愿系数模拟柔性负荷的响应不确定性。通过对混合整数线性规划模型的求解,验证了所提模型的有效性,并得出不同时段在柔性负荷聚合商购买和售出能量的投标策略,为其参与电力市场投标竞价提供决策依据。With the increasing proportion of electric vehicles, distributed energy storages and thermostatically controlled loads connected to the new generation smart grid, flexible load aggregator, as a bidding entity, will be able to participate in day-ahead electricity market. In this paper, we propose that a stochastic robust model for bidding decision-making of flexible load aggregator in the day-ahead market considering uncertainty. The minimal operating costs of flexible load aggregator is the objective function. The uncertainty of day-ahead price is modeled using stochastic scenarios. The uncertainty of driving behaves of electric vehicles and ambient temperature of temperature-controlled loads are modeled using confidence bounds. Uncertainty of flexible load response are modeled using response willing coefficient simulation. By solving the mixed integer linear programming model, the effectiveness of the proposed model is verified by the example, and the bidding strategy for purchasing and selling energy in flexible load aggregator at different time period is obtained. The model will provide decision- making for flexible load aggregator to participate in the bidding of electricity market.
