Abstract:
The objective of the Costa Rica grid feed-in study is to determine theeffect of an increasing amount of wind power on the stability of the
high voltage grid of Costa Rica. Due to a favourable wind climate, the
amount of wind power in Costa Rica is increasing steadily. There is
some concern about the effect of fluctuating wind power on the frequency
and voltage variations of the grid. Especially the loss of a large amount
of wind power in a very short time, 30 second to a few minutes, is expected
to result in a frequency control problem. This study intends to quantify
this problem. The method used is twofold:
- dynamic simulations of the High Voltage grid of Costa Rica, including
existing and future wind farms, are used to study the effect of wind
power variations on the frequency stability;
- the probability of wind speeds exceeding 25 m/s at different locations
at the same time is determined, in order to estimate the chance of cut-out
of a complete wind farm in a short period of time.
