What is the formula for penalty factor?

What is the formula for penalty factor?

C1(PG1) = 10000 Rs/MWhr and C2(PG2) = 12500 Rs/MWhr and the loss in the line is Ploss(pu) = 0.5(PG1)2, where the loss coefficient has been expressed in pu on a base of 100 MVA.

What is penalty factor?

The penalty factor in the power system is a factor by which the incremental cost of power production of the plant must be multiplied to accommodate for the transmission losses. It is also defined as the ratio of power generated by the plant to the actual power demand of the load being met after transmission loss.

What will be the penalty factor for a unit of the generating station is located very close to load?

If generating station is located very close to load centre, Penalty factor is almost equal to unity. Q.

What is optimal dispatch of generation?

Optimal dispatch is the operation of generation facilities to produce energy at the lowest cost to reliability serve consumer, recognizing any operational limit of generation and transmission facilities [1].

What is unit of transmission loss coefficient?

a) MW.

How is incremental cost calculated?

Incremental cost is also referred to as marginal cost. The formula is the same regardless of the terminology choice. You simply divide the change in cost by the change in quantity. Divide the cost by the units manufactured and the result is your incremental or marginal cost.

What are the units of penalty factor Mcq?

Penalty factor in power system is a factor (greater than unity) by which the incremental cost of power production of plant must be multiplied to accommodate for the transmission losses….

• PG 1 = 60 MW, PG 2 = 110 MW.
• PG 1 = 80 MW, PG 2 = 90 MW.
• PG 1 = 100 MW, PG 2 = 70 MW.
• PG 1 = 120 MW, PG 2 = 50 MW.

What is heat rate curve?

The heat rate curve plots the heat energy required per MWH of generated electrical output for the generator as a function of the generator’s MW output. Thus, the heat rate curve indicates the efficiency of the unit over its operating range.

What is exact coordination equation?

Equation (7.23) implies that minimum fuel cost is obtained, when the incremental fuel cost of each plant multiplied by its penalty factor is the same for all the plants. This equation is referred to as the exact coordination equation.

Which is the condition for most economic dispatch?

The above equation shows that the criterion for a most economical division of load between within a plant is that all the unit is must operate at the same incremental fuel cost. This is known as the principle of equal λ criterion or the equal incremental cost-loading principle for economic operation.

What is the exact coordination equation?

Equation (7.23) implies that minimum fuel cost is obtained, when the incremental fuel cost of each plant multiplied by its penalty factor is the same for all the plants. The (k + 1) variables (PG1, PG2,… PGK, λ) can be obtained from k optimal dispatch Eq. This equation is referred to as the exact coordination equation.

How to calculate penalty factor for two generators?

Figure below shows a two generator system supplying a load PD = 40 MW, connected at Bus-2. C1(PG1) = 10000 Rs/MWhr and C2(PG2) = 12500 Rs/MWhr and the loss in the line is Ploss (pu) = 0.5 (PG1)2, where the loss coefficient has been expressed in pu on a base of 100 MVA. Find the most economic power generation schedule of the plants.

Why is generator 1 being penalized for transmission loss?

This is because; generator 1 is being penalized due to additional transmission loss in its power production cost. Thus, penalty factor can also be defined as the ratio of cost incurred when transmission loss is taken into account to the cost incurred without having transmission loss. This definition gives better sense of penalty factor. Isn’t it?

Which is a penalty factor in the power system?

What is Penalty Factor? Penalty Factor in Power System is a factor (greater than unity) by which the incremental cost of power production of plant must be multiplied to accommodate for the transmission losses. It is also defined as the ratio of power generated by the plant to the actual power demand of the load being met after transmission loss.

When to share load between generator 1 and 2?

If generator 2 has local load, the as per the equal incremental production criterion, both the generators should share the load equally (this is because the incremental production cost of both the generators 1 &2 are same).
