Orchestrating Virtual Power Plants: How Low-Code Platforms Bridge the Gap

Our electric grid is changing. For a century, it operated as a one-way street: large, centralized power plants generated electricity and pushed it downstream to homes and businesses. But today, that model is shifting. Rooftop solar panels, home batteries, and electric vehicles (EVs) are turning that one-way street into a dynamic, two-way intersection.

These technologies are known as Distributed Energy Resources (DERs). They promise a cleaner, more resilient, and more flexible energy future. However, with that promise comes a challenge: how do we manage this growing web of distributed systems? How do we coordinate them to work seamlessly with the traditional grid? The answer lies in the concept of the Virtual Power Plant (VPP).

What is a Virtual Power Plant?

A Virtual Power Plant isn’t a physical facility. It’s a software-based system that connects and orchestrates hundreds — sometimes thousands — of DERs into a unified energy asset. Think of it like a conductor of an orchestra: the conductor doesn’t play an instrument, but ensures that every musician plays at the right time and in harmony with the others.

Similarly, a VPP ensures that solar panels, batteries, EVs, and other devices respond to real-time energy conditions. It might tell a group of batteries to store excess solar power during the afternoon or instruct EVs to send power back to the grid during a peak evening demand spike. The goal is coordinated action that supports both local needs and broader grid stability.

Why VPPs Have Been So Hard to Build

While the concept of a VPP is not new, the execution has long been a technical and operational struggle. At the heart of the problem is integration — getting disparate devices and systems to work together.

First, there's the vendor lock-in problem. You might buy a top-tier battery system, only to find it doesn't communicate with your solar inverter from another manufacturer. This limits functionality and undermines the value of your investment.

Second, there's the manual integration nightmare. Engineers often spend weeks writing custom code to onboard new devices — and they must do this over and over for each new asset. It’s time-consuming, expensive, and frustrating.

Third, the data you eventually collect typically comes in inconsistent formats, making it difficult to use without first cleaning and transforming it. Valuable time is lost in standardizing data before any control logic can be applied.

Finally, there's the challenge of scale. As the number and types of assets grow, so do the operational complexities. How do you securely update logic across thousands of devices? How do you ensure uptime and reliability? How do you onboard new assets without starting from scratch every time? Without a centralized management platform, these challenges quickly become overwhelming.

Low-Code: The Universal Translator for the Grid

This is where low-code platforms, like FlowFuse built on Node-RED, come into play. They offer a powerful and accessible way to bridge the technical gap — without reinventing the wheel every time.

Using a low-code platform, an engineer can visually build flows and logic without needing to write large amounts of custom code. This approach dramatically accelerates development and reduces complexity.

For example, connecting to devices becomes as simple as dragging and dropping pre-built nodes. You can pull data from a solar panel using Modbus, a battery using a REST API, and even fetch weather forecasts — all within the same interface.

Once the data is collected, standardizing it is straightforward. JSON, CSV, Change, and function nodes allow you to reformat disparate data streams into a single, consistent structure that the VPP can understand.

Building logic is also visual. You can create rules like: “If the electricity price is high and the batteries are full, then send power to the grid.” Such logic is easy to build, read, and modify — even for teams that aren't deeply technical.

FlowFuse: Scaling and Securing the VPP

Beyond integration, FlowFuse provides the centralized control and management layer that VPPs need to scale. It gives operators a single dashboard to deploy logic, monitor device health, and push updates — regardless of how large or geographically dispersed the device fleet is.

Need to onboard new assets? You can do it from the same platform, without custom scripts or separate tools. This is what makes it possible to scale from managing 100 devices to 10,000 — in a structured, reliable way.

FlowFuse is also designed with industrial-grade security and management capabilities, essential for critical infrastructure environments. Role-based access control, audit logs, and deployment workflows are all built in.

And importantly, FlowFuse supports collaborative development. No more siloed knowledge stuck with one engineer. Teams can work together in a controlled environment, making development faster and more sustainable.

Ready to Build Smarter Energy Systems?

Virtual Power Plants are the future of the energy grid — but building them without the right tools is slow, brittle, and expensive. Low-code platforms like FlowFuse change that. They offer a practical, scalable, and secure way to integrate DERs, manage fleet operations, and coordinate distributed energy like never before.
