Atom Search Optimization-Based PV Array Reconfiguration Technique under Partial Shading Condition

Table 1

The detailed pseudocode of the ASO-based PV reconfiguration method.

---

(1): TCT PV system modelling by equations (1) and (2)

(2): Initialize: algorithms parameters (population number, iteration number, etc.)

(3): Generate PV module shadow distribution randomly

(4): Calculate the output power of each PV array according to equation (5) and keep it as the current optimal output power and optimal shadow distribution

(5): While k ≤ k_max

(6): Update the acceleration of each atom by equation (6)

(7): Update the velocity of each atom by equation (8)

(8): Update the position of each atom by equation (9)

(9): Calculate the output power of each PV array again and update the optimal shadow distribution and optimal output power

(10): Set k = k + 1

(11): End while

(12): Output: best shadow distribution of PV arrays and the maximum output power

(13): Calculate mismatch loss, ff of the optimal solution, and STD of simulation results of ASO in 20 runs
