PowerWorld Applications
Strategic/Economic consulting for transmission &
generation planning
Futuristic Locational Marginal Pricing (LMP) based studies
to asses:
–
Financial Feasibility of planned generation projects
–
Price Signals for siting purposes
–
Decisions on acquisition of Transmission Congestion Rights
(TCR)/Firm Transmission Rights (FTR)
Transmission Assessment Studies – Approximate 200 such
studies spanning ERCOT, NYISO, NE-ISO, CAISO, SPP, PJM,
WECC & MISO regions conducted

Economic Modeling of Emission
Constraints – Overview
Department of Energy (DOE) – Small Business
Innovative Research (SBIR), Phase I awarded under
Electricity System Reliability Model
Collaborative effort between PwrSolutions &
PowerWorld Corporation
Issues development seeks to address:
Quantitative Assessment of impact of new
technologies on:
• Economic performance of National Grid
• Environmental performance of National Grid
• Reliability performance of National Grid
• Security-related performance of National Grid

Economic Modeling of Emission
Constraints – Our Vision
Phase I Objectives
Connect/Link model nomenclature for all applicable data
sources – Access to NEMS
Extension of existing integrated model:
–
Include emission limits associated with operation of specific units
–
Include economic value of emission limits
–
Include transient or dynamic transmission interchange
–
Include variation of transmission interchange based on LMP
Development of user-friendly Graphical User Interface (GUI)
for non-technical entities
