Power System Studies

  • Grid Impact Studies of integration of power plants, conventional or RE, with the main grid.
  • Load flow, optimal power flow, and short circuit analysis for system planning and operation.
  • Dynamic and transient stability analysis for all kinds of disturbances in the system.
  • Voltage stability, voltage control, and voltage collapse analysis and remedies by compensating devices like shunt capacitors/reactors banks, SVCs, FACTS, Series Compensators, and STATCOMs, etc.
  • Small signal stability analysis with remedies by power system stabilizers (PSS) and/or power oscillation damper (POD)in the system.
  • All sorts of transient analyses including but not limited to, transient overvoltage (TOV), transient recovery voltage (TRV), load rejection, in-rush currents, and frequency-scans, etc.
  • Power quality issues like flicker, harmonics/resonance, and voltage-unbalance due to bad loads like arc furnaces in steel mills or non-uniform generations like wind turbines.
  • Engineering, design, and specifications of substations, overhead lines, cables, and FACTS devices (such as SVC/TCSC/STATCOM).
  • Load forecast analysis based on historical data, power market surveys, economic growth indices like GDP or GNP, population growth rates, etc. using econometric models, time-series models, end-users models, etc.
  • Optimized Generation Planning based on reliability indices of LOLE/LOLP, minimum reserve margins, cost of un-served energy, etc. for one integrated system, and for various systems having inter-ties for reserve sharing or fixed bulk transfer of power using multi-area reliability indices.
  • Analysis of transfer limits between different grid systems fulfilling the generation and transmission reliability criteria.
  • Economic and financial analysis of power projects required for approval by funding agencies or governmental authorities.
