氯碱电解为需求侧管理提供了有利的应用前景，几个研究小组已经提出了动态模型，以获得此类应用的最佳轨迹。然而，到目前为止，这些提出的动态模型还没有用真实的工业工厂数据进行验证。这对于确定轨迹是非常重要的，这确实是可行的。这一贡献通过提出氯碱电解的动态模型来解决这一问题，该模型包含与动态操作相关的变量，特别是温度和电解液的组成。该模型用德国MARL电解槽的实际工厂数据进行了验证，有两种情况：(1)几个小的负荷变化约为4 MW；(2)大的负荷变化超过50 MW。
The chlor-alkali electrolysis promises advantageous application of demand-side management and several research groups have proposed dynamic models to obtain optimal trajectories for such applications. However, no dynamic model of those proposed so far has yet been validated with real, industrial plant data. This is highly important to determine trajectories, which are indeed feasible. This contribution addresses this issue by proposing a dynamic model of the chlor-alkali electrolysis that contains those variables relevant for dynamic operation, especially temperature and composition of the electrolytes. This model is validated with real plant data from an electrolysis located in Marl, Germany, for two scenarios: (1) several small load changes of around 4 MW and (2) a large load change of more than 50 MW.
