Use the responsive grid below. Large screens show three columns, medium screens show two, and mobile displays one column.
These sample values match the default form inputs and provide a realistic planning scenario for testing the calculator.
| Category | Input | Value |
|---|---|---|
| System | Load Demand | 480 MW |
| System | Reserve Margin | 10% |
| System | Loss Factor | 4% |
| System | Base MVA | 100 |
| Generator A | Min / Max / a / b / c | 80 / 300 / 0.0045 / 8.5 / 120 |
| Generator B | Min / Max / a / b / c | 60 / 240 / 0.0052 / 7.8 / 95 |
| Generator C | Min / Max / a / b / c | 40 / 200 / 0.0060 / 7.2 / 80 |
| Transmission | Line Shares | 40% / 35% / 25% |
| Transmission | Line Capacities | 240 / 210 / 180 MW |
Reserve MW = Load Demand × Reserve Margin / 100
Net Requirement = Load Demand + Reserve MW
Gross Generation = Net Requirement / (1 − Loss Factor)
C(P) = aP² + bP + c, where P is the generator output in MW.
The page uses constrained lambda iteration. It seeks a common incremental cost while keeping each generator between minimum and maximum output limits.
Line Flow = Load Demand × Normalized Share
Utilization % = Line Flow / Capacity × 100
A practical planning estimate is used: voltage reduces as overload severity and losses rise. This is suitable for screening, not full AC load-flow studies.
It minimizes total generator operating cost while meeting demand, reserve, and loss-adjusted generation needs. It also checks line utilization and adds an overload penalty when flow exceeds capacity.
No. It is a planning-oriented approximation using economic dispatch logic, loss assumptions, and simplified network checks. It is useful for screening and learning, but not for final protection or real-time control decisions.
Users often enter approximate percentages that do not add to exactly 100. The calculator rescales them so total flow remains balanced and the network summary still represents the full load.
The tool flags the case as infeasible and sets each generator to its maximum output. This makes the shortfall visible and highlights the need for more supply or lower demand.
It controls how strongly overload and loss conditions reduce the planning voltage estimate. Higher sensitivity makes the voltage result drop faster under stressed operating conditions.
They define each generator’s quadratic operating cost curve. The a term shapes curvature, b sets the linear slope, and c represents fixed operating cost in the simplified model.
Use it when you want overloaded line conditions to appear more expensive. This helps compare solutions where dispatch may be cheap, but network stress makes the operating point less attractive.
Yes. It is suitable for demonstrations, feasibility checks, coursework, and scenario planning. For production studies, validate results with a detailed network model and engineering review.
