Write a Matlab program with GUI (graphical user interfaces) to solve (1) economic dispatch problems, and (2) power flow problems.
(1) Economic dispatch using Lambda-iteration method:
Input: Quadratic fuel cost function; Total load demand; Generation limits.
Output: Optimal output of each generating unit (kW or MW); incremental cost ($/kWh or $/MWh); Total fuel cost ($/hour); Plot IC curves.
Please find the needed input data or make reasonable assumption.
(2) Power flow: a sample system is shown in Figure 1.
Input: Bus data (Table 1); Line data (Table 2); Select power flow solution algorithms
• Newton-Raphson – power flow solutions (see Table 3) and total power losses in MW and MVAR.
• Decoupled power flow – power flow solutions (see Table 4) and total power losses in MW and MVAR.
• DC (linear) power flow – power flow solutions.
