(3) It can indirectly limit the power transmission on tie lines among areas by processing the
generated output constraints of a multiarea.
(4) It can make power plants operate automatically on the periods of base load or peak load by
adjusting the generated output and generated energy constraints (making them as equal or
unequal constraints).
(5) It can reduce the numbers of integer variables in the optimization calculation. In such a
way, the operating time periods of load curve are divided into three categories: peak,
valley, and outage, upon which the steps of pumped storage are changed, so that
optimization calculation speed is improved.
