Research on the Maximum Penetration Capacity of Distributed PV Based on Firework Algorithm

For the maximum penetration capacity problem of distributed PV, a computational model with power equation, node voltage, line capacity and distributed PV capacity as the main constraints is established, and an improved firework algorithm is proposed to solve the above model. Based on the semi-positive cloud generator to improve the explosion spark generation method, a large number of displacement deviations with stable propensity and randomness are obtained, increasing the population diversity and speeding up the convergence; the dimensional difference strategy is used to improve the variance operator, which is conducive to the search for the late jump out local optimum. Apply the algorithm to the CIGER6 Task Force system and verify the validity of the algorithm. The results show that the proposed algorithm is able to solve the penetration level calculation problem of distributed PV.
