Research on the Assessment Method of Distributed PV Admittance Capacity

As the proportion of distributed PV in distribution grid access increases, it exacerbates the problem of voltage overrun and affects the safe and stable operation of the distribution grid, and there is an urgent need to establish a reasonable assessment system for the acceptance capacity of distributed PV. To establish a distribution network PV acceptance capacity assessment system, the three aspects of grid operation, economy, and PV penetration are synthesized, and several indicators are proposed, such as voltage deviation, return on equipment investment and PV power generation share, and the combination of hierarchical analysis method and principal component analysis is used to assign weights, and a comprehensive assessment system for distributed PV acceptance capacity is established.
