3.1.3. Constraints

During the design of the PV power plant, many constraints are considered to account for the limits of the different parameters of the whole system. The following expression shows the limitation of some variables:

$$N\_{s,\text{min}} \le N\_s \le N\_{s,\text{max}} \tag{3}$$

$$1 \le N\_p \le N\_{p,\text{max}} \tag{4}$$

$$1 \le N\_r \le N\_{r,\text{max}} \tag{5}$$

$$0 \le \beta \le 90\tag{6}$$

$$S\_{occupied} \le Avaalaillearea\tag{7}$$

The following equality constraint expressions were used to select the PV module and inverter from the list of candidates:

$$PV\_1 + PV\_2 + \dots = 1\tag{8}$$

$$INV\_1 + INV\_2 + \dots = 1\tag{9}$$
