如何设计 VPP 虚拟发电网络 - VCC2 公开课（普通话）
This (free) open class will explore how we can use technology and teamwork to create a cleaner, more reliable energy future, and how the math you're learning now, like algebra, is a key part of it!
Here are the topics we will cover:
The Electricity Challenge: Powering Our World
Why do we need electricity, and how much do we use every day? (Think about lights, phones, computers!)
Where does our electricity come from, and what happens when lots of people need it at the same time?
Why is it sometimes tricky to get electricity to everyone, especially from clean sources like sun and wind?
Meet the Energy Helpers: DERs
Electricity doesn't just come from big power plants far away anymore.
Let's meet the "Distributed Energy Resources" (DERs) – small energy helpers located right in our neighborhoods or even homes, like solar panels on roofs, batteries, electric vehicles (EVs), and smart appliances.
How do we measure the energy these helpers make or save? We use units like kilowatts (kW) and kilowatt-hours (kWh). This is like measuring things in science, and math helps us keep track!
Building an Energy Dream Team: Virtual Power Plants (VPPs)
What if all these small helpers could work together like a big, coordinated team? That's the idea behind a Virtual Power Plant (VPP)!.
A VPP isn't a single building, but a smart network connecting many DERs so they can act together.
Imagine them like players on a sports team or instruments in an orchestra, working together guided by smart computer systems.
Playing the Energy Balancing Game: Demand Response
Sometimes the electricity grid gets stressed, like on a very hot day when everyone is using air conditioning.
VPPs help by playing a game called "Demand Response" – they ask our energy helpers to use less electricity or change when they use it for a short time.
Math Challenge: If 100 homes in a VPP agree to use 500 Watts less electricity for 2 hours, how much total energy is saved? (This uses multiplication and units, like in algebra!).
Earning Rewards for Helping: Incentives and Digital Tokens
People and businesses whose energy helpers join the VPP team get rewarded for helping the grid stay stable.
These rewards can be money saved on electricity bills or sometimes special digital "tokens".
How could these tokens work? You might earn tokens for helping balance the grid, maybe use them to pay bills, and some tokens might even be removed from the system over time to keep things working smoothly. Thinking about how the number of tokens changes involves math, just like tracking things with variables in algebra!
The Brains and Nerves of the Team: VPP Technology and Design
What kind of smart technology connects all the helpers and makes the VPP team work?.
We need special devices like "edge hubs" (like a small computer in your home) and "controllers" for appliances to talk to each other and to the cloud.
Designing these systems means figuring out how much energy is being made, used, or stored at any moment. This requires accurate measurement and tracking. Think of how balancing equations in algebra helps us track quantities!
Making it Happen: Funding and Scaling VPPs
It takes money to build these VPP teams and the technology they need! Who helps pay for it?.
Big companies and even governments invest in these projects because they are important for the future.
How do we build more and more VPPs everywhere? It requires lots of investment and proving the technology works well. Math helps investors decide if these projects are a good financial idea by calculating costs and savings.
Your Math Superpowers: Algebra and the Future of Energy
How is the math you learn in school, especially algebra, a superpower for understanding and building VPPs?
Algebra helps us think about unknown amounts (like how much energy a new technology will save) using variables and write equations to show how different things are related (like how many DERs are needed to meet a certain energy need).
We use algebra to calculate energy flow, predict how much energy will be needed, figure out savings, and design efficient systems.
Learning algebra now is giving you the tools to help solve real-world problems like designing the energy systems of the future!
