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)

  • stuff ahh

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
    • example 1
    • example 2

Summary

  • The problems:
    • Cost (Equity)
    • Sustainability (Green)
    • Security

Examples

Shell energy

  • Battery and energy trading
    • shit

TESLA

  • Megapack project: stores energy for the grid reliably and safely.
  • Each unit store a lot of energy, and withstands extreme weathers
