The unconstrained access of distributed PV to the distribution network inevitably affect the security of the power grid. Therefore
a Monte Carlo importance sampling method based on voltage sensitivity is proposed
which considers the timing characteristics of PV and load to evaluate the maximum access capacity of distributed PV under security and energy efficiency constraints. A distribution network security domain model considering the energy efficiency of the system is established
and taking the feeder as the minimum evaluation zone. Then the bisecting -means is used to perform cluster analysis on the PV nodes to be connected based on the voltage sensitivity index and node voltage. According to the clustering results
a Monte Carlo importance sampling method is used to construct a new probabilistic model to randomly generate PV deployment scenarios
which realizes the evaluation of the maximum access capacity of PV in all zones in the security region. The simulation results show that after adopting the security region considering system energy efficiency
the maximum access capacity of PV is only reduced by 0.39% compared to the conventional security region
while the system energy efficiency increases by 4.82%
which improves the system operational efficiency. The evaluation accuracy of the proposed method is improved by 12.41% compared with the analytical optimization algorithm
and the number of deployment scenarios required is reduced by nearly 60% compared to the traditional Monte Carlo simulation method under the same accuracy
which improves the accuracy and efficiency of the evaluation of the maximum PV access capacity of the distribution network.
