【摘要】：建立了可平移负荷、可削减负荷和可转移负荷3类互动负荷模型,应用于用户参与互动环境下微电网日前经济调度,并探讨了用户互动合约的相关内容。可平移负荷模型通过0-1变量和功率分布向量描述,极大地降低了模型求解规模;可削减负荷模型考虑了互动频率和持续时间;可转移负荷模型考虑了可转移时间区间;互动负荷模型均保持线性,求解不依赖于初值。算例验证结果表明:1)所提出的模型充分考虑了互动负荷的用电特点和用户要求,工程实操性强;2)可削减负荷能发挥削峰作用,可平移负荷和可转移负荷实现移峰;3)3类互动负荷相互配合,不仅能合理调整负荷曲线,还能有效消纳新能源出力,以实现系统经济运行。
[Abstract]:In this paper, three kinds of interactive load models, namely, removable load, shedding load and transferable load, are established, which are applied to the pre-day economic dispatch of micro-grid in interactive environment, and the relevant contents of user interaction contract are discussed.The translatable load model is described by 0-1 variables and power distribution vectors, which greatly reduces the scale of the model solution; the scalable load model takes into account the interaction frequency and duration; the transferable load model considers the transferable time interval;The interactive load model is linear, and the solution is independent of the initial value.The simulation results show that the proposed model takes fully into account the characteristics of the interactive load and the user's requirements, and the practical engineering can reduce the load to play the role of peak cutting.There are three kinds of interactive load that can shift the peak and shift the load, which can not only adjust the load curve reasonably, but also effectively absorb the new energy to realize the economic operation of the system.
