Regional voltage layered and distributed cooperative control system of photovoltaic power distribution network
ActiveCN107086578AMaximize power generation efficiencyResolve limit violationsSingle network parallel feeding arrangementsAc network voltage adjustmentOvervoltageTransformer
The invention provides a regional voltage layered and distributed cooperative control system of a photovoltaic power distribution network. When voltage does not exceed the limit on a user layer, local reactive compensation will come into play so as to restrain generation of overvoltage. When feeder line voltage exceeds the limit, the passive compensation of distributed cooperative control comes into play in advance so as to reduce voltage regulation cost. When passive capacity is completely consumed and the voltage still exceeds the limit, an active shrinkage strategy of the distributed cooperative control acquires an optimized photovoltaic active shrinkage solution through little distribution communication and local calculation. When feeder line voltage recovers to normal, through the power recovery control, maximized photovoltaic power generation benefits can be ensured. Through transformer station layer voltage, voltage information and in-station information based on feeder line key nodes are controlled, and by use of a nine-area graph of a fuzzy passive boundary, a limit exceeding problem of the feeder line voltage is solved by adjusting voltage of the low-voltage side of a transformer.

By the flow-collecting control of the flow field, the system changes the wind speed and wind pressure, improves the wind energy density ratio and leads the airflow in nature to be changeable and compressible. When the airflow passes through a vortex body, the pressure of the flow field is changed so that the wind energy conversion ratio of a resistance-typed wind power machine is higher than that of a resistance-increasing wind power machine. A multi-pole differential-speed power generator is suitable for working at a rated power under the minimum and maximum wind speed working condition, thus realizing high-capability assembly of a single unit. The system changes the Betz theory created by Betz who is a famous physical scientist in Germany and is the founder of wind power theory on the basis of natural flow field, and negates the issue that in the Betz theory system, the airflow in the nature can not be compressed and the issue that the wind energy conversion ratio of the resistance-increasing wind power machine is more than that of the resistance-type wind power machine.
