Las respuestas y explicaciones aparecen a medida que realiza el cuestionario.
- ¿Por qué los precios marginales por ubicación difieren de un nodo de la red a otro?
- Each utility sets its own retail rate
- Generators choose different currencies
- Transmission congestion and losses make power costlier to deliver to some locations
- Nodes closer to the equator use more air conditioning
- ¿Cuál es el objetivo principal de los mercados intradiario y en tiempo real o de equilibrio?
- To correct for forecast errors after the day-ahead market clears
- To set long-term fuel contracts
- To replace the day-ahead market entirely
- To decide where new power plants are built
- ¿Por qué decidir cuándo descargar una batería es un problema comercial complicado?
- Batteries cannot sell ancillary services
- Battery output cannot be measured
- Discharging is banned during high prices
- The battery holds limited energy, so discharging now means giving up a possibly higher price later
- ¿Qué aporta la regresión cuantil para la previsión de precios?
- A single exact price for each interval
- Percentile estimates such as the 10th, 50th and 90th, which describe the range of uncertainty
- A list of market participants
- The battery's round-trip efficiency
- ¿Cómo puede un modelo con un error absoluto medio menor ganar menos dinero que uno menos preciso?
- Lower error always means more profit, so it cannot
- Markets pay only for daytime forecasts
- It can get the timing of the daily peak wrong, and that is where most of the revenue is
- Mean absolute error only measures demand
- What mistake do properly built backtests avoid?
- Using information that was not available at bid time, such as data published after gate closure
- Using historical market data at all
- Including battery efficiency losses
- Testing on more than one year of data
- Which EU agency oversees the REMIT rules against energy market manipulation, together with national regulators?
- FERC
- ERCOT
- PJM
- ACER
- What does the guide say about predicting rare scarcity price spikes?
- Neural networks now predict them perfectly
- No model reliably predicts them, so good systems manage the risk instead
- They are caused only by fuel prices, so they are easy to forecast
- They never happen in markets with batteries
