DISCO-wise Peak Demand Forecast (MW)

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  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

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
