Title:
COORDINATION CONTROL METHOD FOR INPUT-PARALLEL OUTPUT-SERIES DIRECT CURRENT BOOST-BASED PHOTOVOLTAIC COLLECTION ACCESS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/075955
Kind Code:
A1
Abstract:
The present invention relates to a coordination control method for an input-parallel output-series (IPOS) direct current (DC) boost-based photovoltaic collection access system, which is used for a photovoltaic grid-connected system comprising a DC boost module and a modular multilevel converter (MMC). The DC boost module uses a structure of IPOS of full bridge isolation DC/DC sub-modules; when a receiving-end grid needs a photovoltaic power station to output the maximum power, the system works at a maximum power control mode, and when the receiving-end grid cannot completely consume the power outputted by the photovoltaic power station, the system works at a power limitation mode.
