Question

b. Power Transmission System Power Balance Management Objectives, Policies and Techniques (Nordic and Finland).

Answer 1

Power balance maintains the balance between production and consumption. Thus the main objective is to maintain uninterrupted power supply to consumers.

The policies for power balance management are.

• To determine the superiority of cores and prioritize the core accordingly.
• To distribute the power fairly based on the required load.
• To optimize the number of bits transfered per second in the core.

The Finlands main grid is synchronous with inter nordic system that connects several contries through direct current connections. The technique to balance the power is indicated by frequency of the grid. If frequency falls below 50Hz then consumption is greater. Thus the production rate must be balanced between 49.9 Hz to 50.1Hz in normal state.The fingrid acquires various reserve product to react to changes in consumption and production.
