Advantages of Grid System

Advantages of Power Grid System:
  1. Exchange of peak loads
  2. Use of older plants
  3. Ensures economical operation
  4. Increases diversity factor
  5. Reduces plant reserve capacity
  6. Increases reliability of supply
  7. Let us discuss each of the advantages in detail

(i) Exchange of peak loads

  • If the load curve of a power station shows a peak demand that is greater than the rated capacity of the plant, then the excess load can be shared by other stations interconnected with it.

(2) Use of Older Plants:

  • The interconnected grid system makes it possible to use the older and less efficient plants to carry peak loads of short duration.

(3) Ensures economical operation:

  • The interconnected grid system makes the operation of concerned power stations quite economical.

(4) Increases diversity factor:

  • The load curves of different interconnected stations are generally different.
  • In other words, the diversity factor of the system is improved, so increasing the effective capacity of the system.

(5) Reduces plant reserve capacity:
Every power station is required to have a standby unit for emergencies.
(6) Increases reliability of supply:

  • If a major breakdown occurs in one station, continuity of the supply can be maintained by other healthy stations.
 Disadvantages Of Grid System
  • Grid software and standards are still evolving
  • Learning curve to get started
  • Non-interactive job submission
