GENERATION PLANNING OBJECTIVE

Generation plan caters the following Aspects:

capacities to install to meet the demand & ensure an

appropriate level of reliability?

to pick the best combination among the different

technologies at hand?

to locate the new generation facilities with respect to fuel

handling , availability of water and requisite infrastructure

facilities?

to incorporate new generation into the system?

Generation Planning Softwares

WASP (Wien Automatic System Planning) 1994 NPP by Acres Canada

SYPCO (System Production Costing Program) 2011 NPSEP by SNC

Lavalin Canada

PDPAT-II Least Cost Generation Plan 2015 by JAICA

PLEXOs Australia (Purchase Under Process)

Power Balance/ Demand Vs Supply

Wien Automatic System Planning (WASP)

Developed by IAEA, Austria

Gives the economically optimal generation expansion plan within user-specified constraints

Used to develop the first National Power Plan (NPP) of WAPDA in 1994

NTDC is currently using WASP-IV (the latest version)

Options for selection of Hydel plants are limited

System Production Costing Program (SYPCO)

Developed by SNC Lavalin International, Canada

Compares the cost of alternative generation

scenarios to serve a given load over a selected period

of time

Was used to develop long term National Power

System Expansion Plan (NPSEP) in 2011

Transmission Planning Objective

Transmission Planning Criteria

Transmission Planning Section is Responsible for:

• Preparing/updating transmission expansion plan.

• Proposing new substations and transmission lines (PC-1).

• Proposing site & Interconnection schemes for power dispersal of all types of new power plants, both in public and private sectors.

• Review of feasibility studies/reports submitted by consultants.

• Providing technical support/consultancy services to the upcoming IPPs, PAEC, WAPDA, GENCO’s, DISCO’s and K-Electric.

• Interaction with NEPRA, MoW&P and International donor agencies for transmission projects/issues.

Transmission planning is based on studies with following two key inputs: Load Forecast Generation Plan

Following studies are carried out with the help of state-of-the-art Power System Simulators for Engineers (PSS/E) software: Load Flow Short Circuit Transient Stability Power Quality Studies

TRANSMISSION PLANNING

Softwares Being Used by Transmission Planning Section

Following software tools, being used by leading consultants and electric utilities worldwide, are available in Planning (Power) Section:

1. Power System Simulator for Engineering (PSS/E) Used for performing load flow, short circuit , transient stability studies

& power quality studies. Used in most of the transmission planning studies.

2. Power System Computer Aided Design (PSCAD) Used for performing electromagnetic switching overvoltage & other

equipment design related studies. Other advanced level equipment design studies, such as, HVDC, FACTS

devices etc.

3. Real Time Power System Simulator (RTPSS) Used for real-time transient analysis Used for relay testing
