Reviewing the challenges to integrating wind

Reviewing the challenges to integrating wind

  • Reliability issues beyond 900 MW – need mitigating measures, resources and the scale/costs escalate rapidly beyond 900 MW

  • Wind power is variable – sometimes unpredictable, increases or decreases rapidly and wind patterns can be counter to load

  • Need dispatchable generation – capability from conventional generation considering physical limits (ramping limits and start up times)

  • Transmission upgrades – need upgrades in SE/SW of the province

  • Large wind potential in Alberta – framework, mitigating measures, obligations and costs were not defined

Adding more wind

Adding more wind

  • To integrate more wind the operator needs to “know what to do” and “have the necessary resources/tools”

  • Current resources/tools

    • The energy merit order

    • Regulating reserves

  • New resources/tools

    • Wind power forecasting

    • Additional regulating reserves

    • Supply / load following service, (i.e. the service would accommodate pumped storage, batteries, others?)

    • Power and/or ramp-rate limiting of wind power facilities

900 MW Threshold


Market and operational framework

Market and Operational Framework

  • Market and Operational Framework (March 2007) replaced the temporary 900 MW threshold – effective September 26, 2007

  • Premise of framework - If the System Operator receives a reasonable forecast of wind power generation, then they can establish an operating plan to accommodate the forecast wind energy by using the following resources/tools:

    • Forecasting

    • The Energy Market Merit Order

    • Regulating Reserves

    • Wind Following Services

    • Wind Power Management

Key mof conclusions

Key MOF Conclusions

  • Wind is not fully dispatchable therefore:

    • Wind Must Forecast supply ‘offer’ (Must Offer = Must Forecast for wind generationWind Power forecasts will not set price - $0/price taker

  • Regulating Reserves and/or Load/Supply Following are Ancillary Services

    • therefore according to current Policy (TDP) and Regulation (TReg) costs will be allocated to load

    • level of reasonable procurement of additional ancillary services is less clear and will be monitored

  • Market participants are obligated to comply with dispatch instructions and directives from the system controller. Wind generators will meet this obligation by:

    • installing power management technology as a condition of service

    • complying with instruction from the system controller to limit output in the event the system cannot absorb all the forecasted or actual wind generation

  • As per TDP, “constrained down payments will not be paid to generators”


What s changed replacing threshold with mof

What’s Changed?Replacing Threshold with MOF

  • Industry acceptance of mitigating tools to manage load-supply balance with increasing supply variability

    • Wind responsibility for power management

  • Industry acceptance order of use of tools

    • Forecasting > Energy Market > Ancillary Services > Wind Power Management

  • Industry acceptance on cost allocation

    • Forecasting – wind generators

    • Ancillary Services – load

    • Power Management costs (operating & capital) – wind generators

  • We have made progress on forecasting and system operator tools


Next steps in wind integration

Next Steps in Wind Integration

  • Currently 497 MW operating on the grid today with;

    • No major operational issues & no increased ancillary services

    • Gaining experience with wind and learning from events

  • 545 MW anticipated by end of 2007

  • 1400 MW can be accommodated with approved transmission upgrades

  • Continued strong interest in wind development in Alberta

  • Implement Market and Operational Framework over the next year or so

Market operations rules procedures

Market & OperationsRules & Procedures

Laura Letourneau


Structure of the iso rules

Structure of the ISO Rules

  • Primarily the combination of three documents:

    • Market Participation Rules

    • Settlement System Code (Load Settlement)

    • Operating Policies & Procedures

  • Public document posted on the AESO web site “www.aeso.ca”


How are iso rules made

How are ISO Rules made?

  • Need identified and reviewed by applicable business area

  • Rule change analysis (add, modify, delete)

  • Initial proposal

  • Stakeholder consultation

  • Recommendation

  • Decision

  • Implementation

    The ISO Rules Change Process is a quarterly cycle and typically takes 4-5 months to complete. Implementation may be delayed, depending on complexity.


Iso rule change process

ISO Rule Change Process


Mof anticipated rule changes

MOF – Anticipated Rule Changes

  • Forecasting requirements

    • Frequency/timing

    • Accuracy/Compliance

  • Power Management procedures

    • Supply Surplus - $0 offer dispatch procedures

    • Other wind power management conditions & curtailment protocol

  • Ancillary Services

    • Refinement/improvements to Operating Reserve Market

    • Development of Supply Following Service

  • Other?


Approach timelines

Approach/Timelines

  • AESO has well established processes for the development and approval of all rule changes (Market/OPP/Settlement)

  • These processes will be used for all rules developed to implement MOF

  • Stakeholders, therefore, have opportunity to provide input/feedback during the consultation stages

  • Timelines for changes are dependent on other work activities

    • Forecasting (interim-earliest mid-08; final-earliest Dec ‘08)

    • Power Management (earliest mid ’08)

    • Ancillary Services


Operating reserves market redesign proposal

Operating Reserves Market Redesign Proposal

  • Timing

    • Proposal will be circulated to industry in October.

    • Opportunities for changes to product on current NGX platform as first phased in step. Interim proposal could envision:

      • change of contract with NGX to address design issues

      • change of procurement to auction format

    • Decisions for Operating Reserve market will be made following normal consultation

    • In the interim, the AESO will continue to procure Operating Reserves to meet forecasts developed by the Operations Planning Group.

      • expect increase in levels as wind is added.

25


Operating reserves market redesign proposal1

Operating Reserves Market Redesign Proposal

  • Current design overly complex for size

    • AESO forecasts operational need at least day ahead

    • AESO as single buyer

    • Price established at equilibrium between bid and offers

    • Misalignment with energy market

  • Proposal to align Operating Reserves (OR) with energy at T-2

    • Dispatch OR offers from merit order instead or “pre-purchasing”

    • Changes to pricing

  • Moving Operating Reserves closer to real time allows for:

    • use of near real-time forecasts

    • Integration of the active and standby products – increasing market depth

    • Convergence and efficiencies of assets across energy and OR

Real time system operation

Real-time system operation

Supply-demand balancing seems simple at first - When demand changes, supply is dispatched up or down to match

The trick is keeping up with changes to prevent large imbalances from occurring - So operators need additional information to help out

Demand

Supply demand balancing input what is changing

Supply-Demand Balancing InputWhat is Changing?

How good is the load forecast today?

What are the Interconnection schedules?

What is the load forecast change? What is the ramp rate?

What generators are still ramping from the last dispatch? How much energy is still to come?

Is the merit order changing?

How good is the wind power forecast today?

What is the wind power forecast? What is the ramp rate?

What is the ramp rate capability in the merit order over the next 10, 20, 30 minutes?

What are the Regulating Reserve units doing?

How much capacity to dispatch to get the required ramp rate?

Do I need to dispatch more ancillary services?

Will I need to activate any Wind Power Management procedures?

Will I need to activate Supply Surplus / Shortfall procedures?

Review of wind power management and the market and operational framework

Review of Wind Power Management and the Market and Operational Framework

  • “ In situations where the system cannot absorb all the forecasted or actual wind power generated, maintaining system security will call for wind power to be dispatched down, ramp rate limited or dispatched off”

  • “This may occur during the following conditions:

    • Forecast loss of wind and insufficient ancillary services or ramping services

    • Supply surplus – thermal units will not be dispatched below minimum stable operating limits

    • Insufficient ancillary services

    • Unforeseen wind conditions


Workgroups and industry representation for wind power management

Workgroups and Industry Representation for Wind Power Management

  • Work groups will implement the Market and Operational Framework for wind power management

  • Work groups will develop recommendations to put forth to industry and stakeholders for consultation

  • Three work groups are proposed primarily due to the different mix of participants required.

    • Work Group #1 - WPF technical requirements

      • AESO, manufacturers, technical staff from wind power developers with operational facilities, new wind developers

    • Work Group #2 - Supply Surplus protocol

      • AESO, Merchant generators, Industrial generators, Importers, Wind power developers from existing facilities, new wind power developers

John Kehler


Background

Background

  • MOF

    • “ The AESO does not expressly have a role in the centralized planning of generation investments. As such, the final arbiter of the value of wind power diversification will be with the investors that allocate capital to specific wind generation facilities”

  • That being said, many stakeholders expressed interest in better understanding diversity and market signals for diversity

  • AESO Response to MOF Comments:

    • “We do intend to conduct further studies to explore the degree and value of diversity as it pertains to the managing wind variability costs and the development and implementation of policy, rules and business practices


Principles where diversity changes the behavior or wind power

Diversity East-West

Principles where Diversity Changes the Behavior or Wind Power

AESO studies indicated that short term variability increases with wind power development “but” not in proportion to growth

AESO studies and observation of the existing WPFs is that diversity has less effect on the long term ramps

Existing WPFs dispersed throughout southern Alberta


What do we know about diversity in alberta today

Diversity East-West

Central

SW

SC

SE

The most amount of correlation observed in 2007

The least amount of correlation observed in 2007

Wind Power Facilities

What do we know about diversity in Alberta today

  • Existing and proposed facilities are dominantly in Southern Alberta

  • For analysis purposes the regions have been identified as SW, SC, SE and Central

  • Existing facilities are in the SW, SC and SE areas and have strong correlation (ramp up or down together) in the 1 hour time frame

  • It is possible that with no threshold that wind power development in Alberta will take on a larger footprint and change the behavior of wind power through diversification


Next steps1

Next Steps

  • Commencing Nov 2007, the AESO will monitor and publish a weekly report that will show the diversity of the operational wind power facilities as well as other operational aspects of wind power generation.

  • The AESO has examined diversity in the data from the 2004 system impact studies and can publish our findings of this work.

  • The AESO will continue to work with the industry and explore the understanding of diversity as wind power developments consumes a larger footprint in Alberta.

  • No specific work group on diversity will be developed at this time.
