针对高比例可再生能源接入下综合能源型虚拟电厂源荷双重不确定性问题,本方法构建了考虑电-热负荷随机波动和风光出力不利偏差的综合能源型虚拟电厂两阶段随机鲁棒优化模型。首先,采用拉丁超立方抽样与K-中心点(K-medoids)聚类生成电、热负荷典型场景,并以场景概率刻画荷侧随机性;其次,采用预算不确定集描述光伏和风电出力偏差,将源侧不确定性嵌入鲁棒优化框架;再次,以先进绝热压缩空气储能(advanced adiabatic compressed air energy storage,AA-CAES)作为综合能源型虚拟电厂的能量枢纽,建立含燃气轮机、电储能、储热罐及外部电网的电-热耦合功率平衡与状态演化模型;最后,利用列与约束生成(column-and-constraint generation,C&CG)算法将原问题分解为主问题和最坏场景子问题进行迭代求解。算例结果表明,在统一源荷测试场景下,当光伏和风电最坏下偏时段数分别为8和12时,该方法的平均总成本和测试最坏总成本较随机优化分别降低192.9元和513.1元,较同预算传统鲁棒优化分别降低59.9元和96.8元。其CVaR90总成本虽较同预算传统鲁棒优化高25.7元,但较随机优化降低507.5元。综合来看,本方法方法在平均运行经济性和极端场景抗风险能力方面表现更优,同时能够显著降低随机优化下的尾部风险,验证了所提两阶段随机鲁棒优化调度方法的有效性。
To address the dual source-load uncertainties of integrated-energy virtual power plants (IEVPPs) under high penetration of renewable energy
this study develops a two-stage stochastic robust optimization model that accounts for IEVPP random electric and thermal load fluctuations alongside adverse photovoltaic and wind power output deviations. First
Latin hypercube sampling and K-medoids clustering are used to generate typical electric and thermal loads
after which load-side uncertainty is characterized via scenario probabilities. Second
a budgeted uncertainty set is adopted to describe photovoltaic and wind power output deviations
thereby incorporating source-side uncertainty into the robust optimization framework. Third
advanced adiabatic compressed air energy storage is utilized as the IEVPP energy hub
and an electric-thermal coupled power balance and state-evolution model is established
encompassing a gas turbine
electric energy storage
a thermal storage tank
and the external power grid. Finally
the column-and-constraint generation algorithm is employed to decompose the original problem into a master problem and a worst-case scenario subproblem for iterative solution.Case study results under unified source-load test scenarios indicate that setting the numbers of worst-case downward deviation periods for photovoltaic and wind power to 8 and 12
respectively
enables the proposed method to reduce the average total cost and worst-case total cost by 192.9 and 513.1 yuan
respectively (compared with stochastic optimization)
and by 59.9 and 96.8 yuan
respectively (compared with traditional robust optimization)
under the same uncertainty budget. Although its CVaR90 total cost is 25.7 yuan higher than that of traditional robust optimization under the same uncertainty budget
it achieves a substantial 507.5 yuan reduction compared with stochastic optimization. Overall
the proposed two-stage stochastic robust optimal scheduling method achieves better performance in terms of average operating economy and extreme-scenario risk resistance while significantly reducing the tail risk.
