摘    要:垃圾焚烧电厂是处理固体废弃物的主要方式之一,并且越来越多的垃圾焚烧电厂具有热电联产模式,既可以在电力市场出售电能,又能为相邻区域供热。基于此,在考虑日前电力市场价格和固体废弃物来量不确定性的前提下,构建了垃圾焚烧热电联产电厂的两阶段鲁棒申报模型。该模型可以在最坏场景下保证垃圾焚烧热电联产电厂的预期收益最大化。为了对模型进行求解,引入Benders分解将该模型分解为易求解的主问题和子问题。最后,算例仿真结果表明,该模型可以帮助运营商制定经济合理的电能申报策略。并通过对比分析和敏感性分析验证了该模型的优越性与适用性。

关 键 词:垃圾焚烧电厂;热电联产模式;鲁棒优化;申报策略;Benders分解

Abstract:Using waste-to-energy plant is one of the main ways of dealing with solid waste. More and more waste-to-energy plants have a combined heat and power model. Plants in this model both heat adjacent areas and sell electricity in the electricity market. Based on this, a two-stage robust trading strategy model of a waste-to-energy combined heat and power (WTE-CHP) plant is constructed considering the uncertainty of the day-ahead market price of electricity and the amount of solid waste. The model can ensure that the expected benefits of WTE-CHP plant are maximized under the worst-case scenario. In order to analyze the model, Benders decomposition is introduced to decompose the model into easy-to-solve main problems and sub-problems. Finally, simulation results show that the model can help operators to formulate economical and reasonable power trading strategies. The superiority and applicability of the model are verified by comparative and sensitivity analysis.
