Bài giảng Power system operation and control - Chapter 3: Transmission system effects - Võ Ngọc Điều

• The network's incremental power losses causes a bias in the optimal economic scheduling of the generators

• the total real power loss increases the total generation demand

• the power flow forms the basis for the development of loss

factors for predicting the real power loss

• the generation schedule may need to be adjusted by shifting

generation to reduce flows on transmission circuits because they would otherwise become overloaded

• difficult to include the last effect into optimum dispatching

• the power flow must be solved to check for violations
