Research On Large Capacity Photovoltaic Power Grid Connected To Henan Power Grid

Photovoltaic solar power is currently the most mature, the most economical way。 Since PV inherently intermittent, random features, and is accompanied by harmonics, dodge, asymmetric power quality problems。How to effectively solve the various problems after large-scale photovoltaic power plants arising from access to technology,it should become the focus of study in the field of photovoltaic.This study was based on the actual situation in different regions of Henan Province,through research in Henan photovoltaic grid Situation, combined with the actual operation of the power grid in the survey, based on a simulation model built by PSCAD, admission photovoltaic power generation capacity through research Henan power, high-capacity access system PV power plant typical pattern etc, depth analysis of Henan photovoltaic power plants can pick how many, how you answered the question, different voltage levels grid PV capacity to accept the proposed calculation method, the typical access different capacities and different PV plant PV-net programs, an example calculation shows that the model containing the PV plant established in this article is accurate and effective, the results are credible。It can be used to guide the access capacity of photovoltaic power plants in Henan Province, the location and access scheme determination to promote a certain sense。...
