优化的一个电池的存储与pyomo

我目前正在努力优化CO2的排放量的一个househould基于电力消耗。 它也包括电池的存储。 但由于某些原因，国家能源计算的新工作。 我不断收到这个错误：

WARNING: Implicitly replacing the Component attribute soe (type=<class
    'pyomo.core.base.var.IndexedVar'>) on block unknown with a new Component
    (type=<class 'pyomo.core.base.constraint.IndexedConstraint'>). This is
    usually indicative of a modelling error. To avoid this warning, use
    block.del_component() and block.add_component().

Restarting kernel...

这是我的代码迄今为止:

    if t == 1:
        return model.soe[t] == soe_start
    else:
        return model.soe[t] == model.soe[t-1] + (model.charge[t] * in_out_efficiency) - model.discharge[t] / in_out_efficiency

存储ist应该是空的开始和结束。
