Answer:
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. Let me understand this more clearly.
Explanation:
As we know that, for economic load dispatch, the incremental production cost of all operating plants should be equal. But this criterion is true only if the load and the power generating plants are localized. This means the power generated by the plant is supplies only the local loads. Suppose there is “n” number of power plants supplying the local loads (load center is nearby the generating station). To meet the power demand of PD, all these “n” plants should be so operated that their incremental power cost is same.
If F be the fuel cost in Rs. per hour for power P MW, then the incremental power cost will be (dF/dP). Note that, the unit of this incremental cost is Rs. per MWhr. If F1, F2, F3,…Fn be the fuel cost for power P1, P2, P3,….Pn, then as per equal incremental cost criteria,
If F be the fuel cost in Rs. per hour for power P MW, then the incremental power cost will be (dF/dP). Note that, the unit of this incremental cost is Rs. per MWhr. If F1, F2, F3,…Fn be the fuel cost for power P1, P2, P3,….Pn, then as per equal incremental cost criteria,(dF1/dP1) = (dF2/dP2)=…….=(dFn/dPn) = λ (say) ……(1)
for optimal operation of system for economic load dispatch. Here λ is incremental cost of power production in Rs. per MWhr.
