4.5 REPRESENTATION OF LOADS
The loads generally consist of industrial and domestic components. The magnitude of the load changes continuously such that the load forecasting problem is truly a statistical one. An industrial load consists mainly of large three phase induction motors with sufficient load constancy and predictable duty cycle, whereas the domestic load mainly consists of lighting, heating and many single-phase devices used at random by householders. The design and operation of power systems both economically and electrically, are greatly influenced by the nature and magnitude of loads. In general, there are three ways of load representation. They are:
- Constant power representation: This is used in load flow studies both specified ...
