Embodiment Construction
[0040] A coordinated control method adapted to real-time scheduling and AGC after large-scale photovoltaic grid-connected, characterized in that it includes the following steps:
[0041] (1) The method of coordination and cooperation between real-time dispatch and AGC: real-time dispatch adopts the method of issuing planned values or directly issuing remote adjustment instructions, which is different from the issuance of AGC remote control instructions. The coordination and cooperation between real-time dispatch and AGC can be Through the following three ways to achieve.
[0042] 1) The real-time power generation plan is issued separately, and some AGC units are dispatched as real-time dispatching units to implement the real-time power generation plan, and the remaining AGC units still execute AGC control instructions;
[0043] 2), AGC unit base point power P B and regulation power P R , AGC base point power P B As a real-time power generation plan, the AGC unit adjusts t...
