What is planning in power system?

Planning for power systems is essentially a projection of how the system should grow over a specific period of time, given certain assumptions and judgment about the future loads and the size of investment in generating capacity additions and transmission facilities expansion and reinforcements.

What are the main objectives and types of planning in power system?

The objective of power system planning is the determination and justification of system topologies, schemes for substations and the main parameters of equipment con- sidering the criteria of economy, security and reliability.

Why reliability is important for power system planning?

Reliability evaluation of electric power systems is an essential and vital issue in the planning, designing, and operation of power systems. The system is deemed to operate successfully if there is enough generation capacity (adequate reserve) to satisfy the peak load (maximum demand).

What is the goal of power system?

Traditionally, the overall objective of power system op- eration is reliable supply of electrical energy to a passive consumer. Modern energy systems combine this objective with the goal of a sustainable and economical allocation of energy sources.

What is the need for system analysis in planning and operation of power system?

The goals of power system analysis are the following: To model or to execute per phase analysis of power system components. To monitor the voltage at different buses, real and reactive power flow between buses. To plan future expansion of the current system.

What are the requirements of a good power system?

The 3 main requirements of a good electrical power distribution. Safety. Efficiency. Reliability.

Why is it important to accurately determine the capacity of a power system?

It is important, because the size or capacity (and therefore cost) of power system components are determined to a great extent by their capability to handle peak power flows.

What is the power system reliability?

In general way, power system reliability addresses the issues of service interruption and power supply loss. In several cases, it is defined as an objective to attempt in terms of indices directly related to the customer. Typical reliability index values for US utilities are SAIFI, SAIDI, and CAIDI.

What is the end function of any power system?

Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers.

Why power system analysis is required?

Power system analyses are an essential part of electrical power system design. Calculations and simulations are performed to verify that the electrical system, including the system components, are correctly specified to perform as intended, withstand expected stress and be protected against failures.
