【AlphaESS VPP 103】The VPP Dispatch Platform: Unlocking New Potential in Australia Energy Sector

Australia is leading the way in energy innovation, with Virtual Power Plants (VPPs) emerging as powerful tools to optimize how electricity is generated, stored, and distributed. By aggregating various Distributed Energy Resources (DERs), VPPs create more resilient and efficient energy systems, helping to stabilize the grid and enable a smooth transition to renewable energy.

VPP Market Trading Mechanism: Unlocking Value for Distributed Energy Resources (DERs)

At its core, a Virtual Power Plant aggregates Distributed Energy Resources (DERs) such as solar panels, wind turbines, and energy storage systems, enabling them to act as a unified, flexible energy provider. This collective management allows VPPs to balance supply and demand more effectively, facilitating the integration of renewable energy into the grid.

In traditional energy markets, smaller power generators often face challenges in meeting minimum bid sizes or dealing with inconsistent output. VPPs solve this by aggregating these resources, allowing for grid participation and enhanced efficiency. Through intelligent market trading, VPPs improve grid stability, making them indispensable in today's energy landscape.

In Australia, a range of participants—from residential customers to large industrial players—partner with Virtual Power Plant (VPP) platforms. These collaborations involve various stakeholders, including energy retailers (who often act as aggregators), renewable energy suppliers, and end users. By integrating energy storage systems into VPPs, these partnerships enable efficient energy management and allow users to generate additional revenue based on their system's capacity and the energy they provide to the grid.

The illustration below shows the roles of key participants in the Australian VPP electricity market and their interactions for efficient energy management.

VPP Dispatch Platform: Driving Smart Energy Management

The VPP Dispatch Platform integrates IoT communication, AI-powered forecasting, and big data analytics to optimize energy usage, ensuring both reliability and profitability for users. It connects with grid operators, energy trading platforms, and edge servers to manage resources, implement plans, and handle operations.

Edge Server: Gathers and analyzes data, manages local operations, or follows control strategies from the central platform.

Devices: Collect data and execute control actions to optimize energy use.

Here are some of the platform's standout features:

1. Real-Time Market Trading:

The platform leverages real-time electricity price fluctuations to dynamically adjust the charge and discharge strategies of connected energy storage systems. What sets our system apart from traditional solutions is its intelligent management of controllable loads, maximizing user profits.

• When electricity prices are high, the power of major loads like heat pumps and air conditioners is reduced, while non-essential loads such as humidifiers and fish tank heaters are turned off.

• During periods of low or negative electricity prices, the platform optimizes battery charging based on user habits and battery state of charge (SOC). Controllable loads, like air conditioners, are increased to take advantage of cheaper electricity.

2. AI-Driven Smart Feed-In:

Utilizing weather forecasts and AI-powered predictions for solar generation, user loads, and battery SOC, the platform pre-plans optimal energy usage strategies.

By default, the energy generated is used in the following order: User Loads -> Battery Storage -> Grid Feed-In. When "Smart Feed-In" is activated, the system intelligently adjusts priorities based on real-time data and predictions, optimizing returns for users.

3. Smart On-Grid/Zero Feed-in Switching:

When the grid experiences negative electricity prices, the platform can intelligently switch to 'Zero Feed-in' mode, protecting users from losses. Once prices rebound, the platform seamlessly resumes grid feed-in, enhancing profitability.

4. Frequency Control Ancillary Services (FCAS):

The platform also plays a crucial role in maintaining grid frequency stability, a key aspect of grid reliability. By participating in different levels of FCAS, users can further optimize their energy dispatch strategies, boosting their overall earnings.

How AlphaESS Systems Contribute to the VPP Response Process

Let's use the AlphaESS SMILE-G3-S5 residential energy storage system as an example to illustrate its role in Australia's FCAS response process. It operates in three key phases:

1. VPP Instructions: The VPP operator sends FCAS instructions to signed customers' devices via the VPP dispatch platform, reserving part of the device's capacity in advance for a specific time.

2. AlphaCloud Communication: Upon receiving these instructions, AlphaCloud—the EMS platform for AlphaESS devices—relays them to the target device using its serial number for precise identification.

3. Device Response: The SMILE-G3-S5 system reserves part of its battery capacity during the set period to respond to frequency changes. The inverter's grid port collects data every 50 milliseconds, and when a frequency deviation occurs, the device adjusts by charging or discharging to stabilize the grid frequency.

AlphaESS SMILE-G3-S5 supports 'Very Fast FCAS' emergency response with a stable 1C charge/discharge capacity. It transitions from zero to full power in under 116 milliseconds, delivering near-instant ancillary services to the electricity market and maximizing trading profits.
