Real-Time Battery Optimization: Maximizing Profits in Dynamic Energy Markets

The Rise of Battery Storage in Modern Energy Markets

As the energy landscape continues to evolve, battery storage has emerged as a critical component in the transition to renewable energy sources. With the increasing maturity of markets like Great Britain and Germany, it has become evident that multi-market optimization and revenue stream stacking are essential for ensuring the sustainability of investments in battery storage systems.

Smart Pulse Technology: An All-in-One Solution

Smart Pulse Technology offers a comprehensive platform that combines various disciplines under one umbrella:

• Fast algorithmic trading engine
• Advanced mathematical models and data science
• Real-time control and monitoring of sites and batteries
• Extensive European market coverage

It's important to note that Smart Pulse is not an optimizer or market participant. Instead, they provide technology to equip clients such as independent power producers, battery owners, optimizers, and aggregators with the tools necessary to deliver their services effectively.

Key Components of the Battery Management System

Optimization Engine

At the heart of the system lies the optimization engine, acting as the brain of the entire operation. This component is responsible for making critical decisions based on market conditions and battery parameters.

EMS Integrator

The EMS (Energy Management System) integrator allows for seamless connection to various devices and systems:

• SCADA devices
• EMS devices
• Other industrial protocols

This component enables the system to:

• Send schedules
• Control devices in real-time
• Receive real-time information from the site

Auto Trader and Scheduling

This module connects to exchanges and executes trades across different marketplaces:

• TSO (Transmission System Operator) markets
• Exchange markets

The entire system must work in perfect harmony, like a well-rehearsed orchestra, with iterations occurring every second or minute to ensure optimal performance.

Real-World Intraday Trading Example

Let's examine a simplified real-world scenario to understand how the system operates:

Initial Trading Phase

• At 3 PM, contracts open for the next day
• Prices fluctuate rapidly
• Fast decision-making algorithms are crucial to capture the best available prices and spreads

Complexity of Price Determination

• Prices vary based on trading volume (e.g., 5 MW vs. 10 MW)
• The optimizer must consider these variations when making decisions

Example Scenario

• 10 MW/10 MWh battery, initially half-filled
• Optimizer captures the largest spread and executes trades
• Initial applicable price for unit discharge energy: €155 per MWh

Dynamic Optimization

• Market conditions change rapidly (minutes or hours later)
• Order book shape evolves, presenting new opportunities
• Optimization engine automatically finds the best opportunities to:
  • Sell back previously bought energy
  • Move buy orders to better-priced contracts
  • Buy back previously sold energy and move to better-priced contracts

Financial Benefits

• No additional battery cycles added (no increased degradation)
• Margins improve from €160 to €188.4 per MWh through financial cycles

Behind the Scenes: The Optimization Process

1. Technical data pulled from EMS integrator
2. Data pushed to optimization engine
3. Execution orders generated and sent to auto trader
4. Auto trader receives market results
5. Results sent back to optimization engine
6. Optimized schedule determined
7. Schedule sent to EMS integrator for implementation

This process occurs frequently to capture all market opportunities and avoid missing potential profits.

Advanced Optimization Considerations

Battery State of Charge

Deciding on the optimal state of charge involves several factors:

• Assigning value to remaining energy in the battery
• Inputting future price forecasts
• Capturing arbitrage opportunities between days
• Optimizing across multiple days (e.g., filling battery on low-price days for use on high-price days)

Efficiency Considerations

• Theoretical vs. actual efficiency
• Environmental conditions impact
• Varying efficiency at different charge levels
• Real-time feedback to train the model on actual efficiency

Human Insight and Strategy

While automation is crucial, human insight remains valuable:

• Traders provide strategy input
• General ballpark cycle cost limits trading frequency
• Detailed parameters can be entered:
  • Minimum sell prices
  • Maximum buy prices
  • "Do not sell until" prices
  • Price forecasts (imbalance, intraday)

Real-World Complexities

Actual battery optimization scenarios are far more complex than simplified examples:

Time Intervals

• 15-minute contracts
• 30-minute contracts
• Hourly contracts
• Cross-product optimization

Multi-Market Optimization

• Intraday markets
• mFRR (manual Frequency Restoration Reserve)
• aFRR (automatic Frequency Restoration Reserve)
• Capacity market commitments

Additional Factors

• Collocation with renewable assets
• Imbalance risks
• Grid constraints
• Multiple battery management under one portfolio
• Degradation cost considerations

Key Components for Successful Operation

1. Optimization algorithm
2. EMS provider connectivity
3. TSO integration module for ancillary service market participation
4. Scheduling system for TSO nominations
5. Dynamic intraday trading system for co-optimization
