In this context, the required technical activities can be clustered as
follows:
Generation:
- Assessment of the impact into the power system of new power plants
either conventional or from RES
- Assessment of the maximum penetration level of non-programmable RES
generation
Grid:
- Identification of the optimal network expansion plans both at the
transmission and distribution level
- Identification of the optimal network operational configurations both
at the transmission and distribution level
- Interconnection studies , - Cost-benefit analyses
- Reliability analysis , - Protection coordination
- Optimal shunt Var compensation , - System performance studies:
o In static conditions
o In dynamic conditions: transient stability, inter-area oscillations,
voltage stability, frequency stability, sub synchronous resonances,
electromagnetic transients (switching and temporary over voltages,
lightning)
o Power quality: harmonics, flicker, voltage dips and identification of
the relevant measures to mitigate the disturbances.
