    Study Notes

    Smart Electricity Systems: User Participation and Demand Response

    • The presentation covers "Smart Electricity Systems", focusing on user participation and demand response.
    • The speaker, Prof. Gianfranco Chicco, from Politecnico di Torino, discusses load management techniques.

    Demand Side Management (DSM)

    • DSM techniques were developed in the 1980s.
    • The objectives of DSM programs were to create variable electrical load patterns over time.
    • Key principles include peak shaving, valley filling, load shifting, strategic load reduction (conservation), strategic load growth, and flexible load shapes.

    DSM Basic Principles

    • Peak clipping: Reducing peak demand.
    • Valley filling: Increasing load during low-demand periods.
    • Load shifting: Changing the timing of load consumption.
    • Strategic load reduction: Reducing load during periods of high demand.
    • Strategic load growth: Increasing load during periods of lower demand.
    • Flexible load shape: Creating a more even load profile.

    Evolution of Tariff Structures

    • Time-of-Use (TOU) rates: Different rates are applied at different times of the day (eg. peak-intermediate-low load periods). The aim is to shift usage to off-peak hours. Rates are designed in advance for a fairly long period (e.g., a year).
    • Real-Time Pricing (RTP): Tariffs are adjusted in real-time, offering more dynamic pricing. Rates can be known as far in advance as the day before.
    • Spot Pricing (SP): Offers the most immediate pricing, changing minute by minute.

    Load Management Today

    • Current load management includes different customer participation levels.
    • Load Shedding (LS): System operator takes action to cut loads during emergencies, without customer involvement.
    • Interruptible Load Management (ILM): Customers agree to specific power reduction plans in exchange for compensation/incentives/remuneration.
    • Real-Time Pricing (RTP): Electricity rates vary dynamically depending on time of day based on calculations done by the provider.
    • Demand Response (DR): Customer's voluntarily reduce electricity consumption, triggered by incentive pricing. Aims are to enhance the efficiency and effectiveness of energy supply; reduced demand peaks, and greater supply efficiency.
    • Direct Load Control (DLC): Active (often automated) power control, often with customer input, to change demand patterns and comply with provider/operator demands

    Controllable Loads

    • Electric heating, air conditioning, refrigeration are controllable based on temperature settings or adjustable timing.
    • Lighting control also possible in groups with differing priorities.
    • Control of low priority appliances possible through intermittent interruptions without affecting major appliance utility.

    Deferrable and Curtailable Loads

    • Deferrable loads: Non-flexible loads (eg. washing machines), or those with flexibility in starting time/schedules (eg. Electric Vehicles).
    • Curtailable loads: Partially or Fully curtailable load, such as air conditioning and light bulbs which do not materially affect their function by being temporarily switched off.

    Demand Response

    • Demand Response is a change in user consumption in response to system programs.
    • Categorizing by Incentives:
      • Classical incentivised programmes
      • Market-based programs
    • Categorizing by Price Signals:
      • Price-based programs
        • Time-of-use
        • Critical Peak Pricing
        • Extreme Day Pricing

    Costs and Benefits of Demand Response

    • Costs: Initial investment in technology, customer education, and running costs.
    • Benefits: Reducing peak loads, creating greater system reliability, and reducing infrastructure costs. Incentive payments and bill savings.

    Benefits for the System

    • Prevent problems arising due to increased consumption and/or lack of supply capacity.
    • System operators can accurately predict/monitor load and act based on expected high/low load periods.
    • Effective regulation and provision of consumer incentives lead to a coordinated response.

    Demand Response in Europe

    • Regulation, and consumer access to providers, are key to effective participation.

    Baseline and Outcomes

    • Need for accurate baseline and data, without irregular/suspicious responses which may give biased results by "gaming" the system.
    • The importance of setting up a simple structure for straightforward calculations and interpretations.

    Adjusted Baselines

    • The revised calculation ensures that the baseline is aligned with current consumption patterns, removing the need to use estimates.
    • Methods for the calculations are provided, along with the data and variables (e.g. time interval/windows, day/timing of data collection).
    • Rules exist to provide a clear method.

    Strategic Behaviour Considerations

    • It is imperative to avoid situations where users act strategically to manipulate the baseline, impacting pricing and performance targets for demand response efforts.
