Calculation of Distributed Photovoltaic Grid Acceptance Capacity Considering Timing Characteristics of Photovoltaic Output

摘要

The smart power network is development trend of the modern power system, which is an important carrier and composition part for current energy source revolution in the world. Construction of the smart power network brings profound influence on the traditional power distribution network. Development mode, structure function, operation characteristic and comprehensive benefit etc aspects of the smart power distribution network will change obviously, the double flows caused by access of the distribution type photovoltaic is one of the important change of the smart power distribution network. Access way and access scale of the distribution type photovoltaic will directly affect planning and construction of the power distribution network in future, and output time series characteristic of photovoltaic also increases complication degree of photovoltaic acceptance capacity calculation. This paper establishes the optimization model of the photovoltaic acceptance capacity counting output time series characteristic of photovoltaic, which studies maximum acceptance capacity of the distribution type photovoltaic considering stable restrain. The sample shows the analysis method forwarded in this paper is applicable to maximum acceptance capacity analysis of photovoltaic meeting with stable restrain of the system.
