Advantages of the Electricity Spot Market
Experience the Flexibility of the Electricity Spot Market!
The electricity spot market is a dynamic component of the broader power market, offering several key advantages. It attracts competitors through effective price signals and ensures consistent price transparency. Both consumers and generators benefit from the positive outcomes facilitated by the spot market. Unlike long-term bilateral contracts, the spot market provides flexibility in trading for both generators and consumers, allowing traders to freely manage their trading schedules up to a day in advance.
Operational Strategy
Smart Energy Storage for a Balanced Grid!
The energy storage system charges when solar output is high (typically during the day) and grid demand is low. Conversely, it discharges when solar output is low (such as at night) and grid demand is high. This strategy helps balance grid supply and demand, reducing the need to purchase expensive peak power.
Arbitrage and Output Smoothing
Maximizing Profits and Stabilizing Power Supply with Arbitrage and Output Smoothing
By capitalizing on price differences across different times of day, the system charges when electricity prices are low and discharges when prices are high, generating additional revenue through market arbitrage. Simultaneously, the energy storage system smooths the output of the photovoltaic plant, reducing fluctuations caused by weather changes and enhancing overall power quality.
Frequency Regulation and Grid Support Services
Stabilize, Support, Secure
The energy storage system swiftly responds to changes in grid frequency, offering frequency regulation services to maintain stability. It also serves as backup capacity, providing rapid response to unexpected grid events. Additionally, the system supplies reactive power support to improve voltage quality, ensuring a more stable and reliable grid.
Energy Management System (EMS) with Predictive Capabilities
Predict, Manage, and Optimize
The Energy Management System (EMS) utilizes smart algorithms to manage the charging and discharging strategies of the energy storage system while interacting with the grid. Through predictive models driven by historical data and machine learning, it forecasts solar output, electricity prices, and load demand. Designed as a high-voltage grid-connected frequency regulation system, it meets both primary and secondary frequency regulation requirements. Frequency regulation is essential for maintaining grid stability and ensuring a balance between supply and demand, making energy storage systems with their rapid response and high flexibility the ideal solution for this critical function.
Project Summary
