The invention relates to an optimal strategy and performance evaluation method controlled by a multi-target section tidal current, comprising the following steps of establishing a main control region in a system; controlling conventional regions of an interconnected power grid with a control target of establishing a section mode by maintaining a frequency of the power grid within a control range,keeping the exchange power among regions of the power grid at a planning value and taking the control of the electric connection relationship in the regions as a basis; and introducing a daily plan and a control bandwidth to a section, wherein the daily plan is used as a middle base value of the control target, and the middle base value and the control bandwidth commonly form a section control target band. The control target of the section is to participate in power regulation of the main control region in the premise of ensuring that the control target is in the section control target band. The invention can control
