I. Introduction:

\(\bullet\) This system consists of six thermal units and based on IEEE 30 bus system \(\rightarrow\) please refer to our PF Library
\(\bullet\) The load demand is 2.834 per unit (p.u.). Some researchers could evaluate their proposed optimization algorithms with different load demands as in [3].
\(\bullet\) The fuel-cost function of this test system is modeled using the quadratic cost function as follows:

\(C_i\left(P_i\right) = a_i + b_i P_i + c_i P^2_i \) .......... \((1)\)

   where \(a_i\), \(b_i\), and \(c_i\) are the function coefficients and tabulated in Table 1.

\(\bullet\) The network losses are modeled using Kron's loss formula as follows:

\(P_L = \sum_{i=1}^{n} \sum_{j=1}^{n} P_i B_{ij} P_j + \sum_{i=1}^{n} B_{0i} P_i + B_{00}\) .......... \((2)\)

   where \(B_{ij}\), \(B_{0i}\), and \(B_{00}\) are called loss coefficients (or just B-coefficients) and listed below:

\(B_{ij}=\begin{bmatrix}
0.02180 & 0.01070 & -0.00036 & -0.00110 & 0.00055 & 0.00330 \\
0.01070 & 0.01704 & -0.00010 & -0.00179 & 0.00026 & 0.00280 \\
-0.00040 & -0.00010 & 0.02459 & -0.01328 & -0.01180 & -0.00790 \\
-0.00110 & -0.00179 & -0.01328 & 0.02650 & 0.00980 & 0.00450 \\
0.00055 & 0.00026 & -0.01180 & 0.00980 & 0.02160 & -0.00010 \\
0.00330 & 0.00280 & -0.00790 & 0.00450 & -0.00010 & 0.02978\end{bmatrix}\)

\(B_{0i} = 10^{-3} \times \left[0.010731,1.7704,-4.0645,3.8453,1.3832,5.5503\right]\)

\(B_{00} = 0.0014\)

\(\bullet\) If the emission-rates are considered, then the following equation can be used to express these rates in the optimization problem:

\(E\left(\sum_{i=1}^n P_i\right) = \sum_{i=1}^n 10^{-2} \left(\alpha_i + \beta_i P_i + \gamma_i P^2_i \right) + \xi_i e^{\delta_i P_i}\) .......... \((3)\)

   where \(\alpha_i\), \(\beta_i\), \(\gamma_i\), \(\xi_i\), and \(\delta_i\) are the coefficients of the \(i\)th unit emission characteristics. Thus, Table 1 is expanded to Table 2 [4].
