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
- Price-based programs
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.
