# Smart Grid Ethan Version
|
||
|
|
|
||
|
|
## Definition
|
||
|
|
|
||
|
|
- Definition of electrical grid:
|
||
|
|
- Power station does **generation and storage**
|
||
|
|
- Transformers, lines are the **transmission** and **distribution**
|
||
|
|
- Electricity retailer sell electricity to **consumers**
|
||
|
|
|
||
|
|
## Present state
|
||
|
|
|
||
|
|
- same as above
|
||
|
|
- Generation
|
||
|
|
- Transmission
|
||
|
|
- Distribution
|
||
|
|
- TO customer
|
||
|
|
- Industrial, commercial, residential
|
||
|
|
|
||
|
|
## Perspective
|
||
|
|
|
||
|
|
- Combine present grid grid with new technology: present + future
|
||
|
|
- Futuristic grid: reasons
|
||
|
|
- New technologies
|
||
|
|
- Customer likes improvements
|
||
|
|
- More data
|
||
|
|
- AI
|
||
|
|
- Climate change
|
||
|
|
|
||
|
|
## Challenges
|
||
|
|
|
||
|
|
- Pattern of electricity usage varies
|
||
|
|
- Renewable energy are not continuous (intermittent)
|
||
|
|
- Seasonality: Summer and winter differences
|
||
|
|
- Power plants has different responding times and prices
|
||
|
|
- Electric trading is complex (P2P electricity)
|
||
|
|
- Usage of Electric stuff: EV, IoT
|
||
|
|
- Climate change
|
||
|
|
- Network transmission need the capacity
|
||
|
|
|
||
|
|
## Electricity market
|
||
|
|
|
||
|
|
- A market mechanism to buy additional energy when demand is high, and sell when
|
||
|
|
demand is low.
|
||
|
|
- High demand and low supply causes price increase
|
||
|
|
- Low demand and high supply cause price decrease
|
||
|
|
- Introduce a exchange market, that electricity resellers and major consumers
|
||
|
|
can buy from both exchange and from power plants
|
||
|
|
|
||
|
|
## Data flow
|
||
|
|
|
||
|
|
### Intro (WTF)
|
||
|
|
|
||
|
|
- 
|
||
|
|
|
||
|
|
### Integrating data with ML
|
||
|
|
|
||
|
|
- For demand forecasting: for the demand in the long term
|
||
|
|
- Use population data, energy price, share of renewable energy and GDP to
|
||
|
|
predict future energy consumption
|
||
|
|
- Demand time series forecasting: for the demand in a time interval
|
||
|
|

|
||
|
|

|
|
|

|
|
## Summary
|
||
|
|
|
||
|
|
- The problems:
|
||
|
|
- Cost (Equity)
|
||
|
|
- Sustainability (Green)
|
||
|
|
- Security
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
### Shell energy
|
||
|
|
|
||
|
|
- Battery and energy trading
|
||
|
|
- 
|
||
|
|
|
||
|
|
### TESLA
|
||
|
|
|
||
|
|
- Megapack project: stores energy for the grid reliably and safely.
|
||
|
|
- Each unit store a lot of energy, and withstands extreme weathers
