Computing the Maximum Permitted Capacity of Distributed PV in Distribution Network

Targeting at the permitted capacity calculation of distributed photovoltaic (PV) system connected by distribution network, a matrix description method was put forward to solve the problem. In this method, the maximum sum of distributed PV permitted penetration capacity is taken as the objective function, and the power flow constraint is replaced by the voltage drop constraint. This avoids the problem of power flow iteration when applying voltage constraints. Finally, the effectiveness of the proposed method is verified using the example analysis of IEEE11 bus system.
