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

• f 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
• f all types of new power plants, both in public and private

sectors.

• Review
• f

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
