Paliza, Ph.D.,Paliza Consulting, LLC. ,2,Agenda,FERC SMD Focus is in the RTM, DAM, and FTRs What is missing in the SMD? Inter-ITP coordination Midwest Markets

2、Initiative MISO-SPP MISO-PJM-SPP joint and common market,Paliza Consulting, LLC. ,3,FERC SMD,Sets the direction for the design and implementation of wholesale markets. Defines the desired end state for these markets. Does not provide solution for transitional issues although establishes principles t

Provides flexibility in regards to timing of the implementation and in accommodating regional differences.,Paliza Consulting, LLC. ,4,Basic Elements of the SMD,From an operational perspective: Real-time market Day-ahead market Ancillary services market Congestion revenue rights market

6、ll ensure that all market participants have equal access to the spot market. RTM main component is a bid-based security constrained dispatch (5 min cycle). RTM is a voluntary market. Market participants can submit: Bilateral schedules, Self-schedule, or Bid into the real-time market,Paliza Consultin

10、ongestion costs in LMP calculation Nodal pricing results in cost causation for congestion pricing to market participants,Paliza Consulting, LLC. ,10,Real-time Market Settlements,All real-time injections, withdrawals and transmission congestion will be settled at LMP prices determined by the real-tim

11、e dispatch. The difference in LMP prices across the grid will reflect congestion and incremental cost of losses. Loads have the choice to settle at nodal or zonal prices. Generators may self-schedule but only accepted schedules will settle at LMP prices.,Paliza Consulting, LLC. ,11,LMP Definition,Ma

13、t (DAM),DAM main component is a bid-based security constrained unit commitment. It is a voluntary market and is financially binding. DAM main function is to provide certainty for Market Participants (MPs). In the DAM, participants will be able to: Buy/sell energy and self-schedule generation. Submit

14、 bilateral transactions. Submit virtual bids.,Paliza Consulting, LLC. ,13,Day-ahead Market Settlements,Process is very similar to RTM settlement for energy, congestion, and losses. RTM settles deviations with respect to DAM schedules. FTRs are settled based on the DAM hourly prices.,Paliza Consultin

15、g, LLC. ,14,Paliza Consulting, LLC. ,15,Day-ahead Reliability Check,Check is performed after DAM closes and it focuses on: Evaluating overall resource adequacy. Evaluating reserve adequacy. Evaluating transmission reliability. Reliability Commitment: Units are committed/de-committed to satisfy relia

16、bility criteria.,Paliza Consulting, LLC. ,16,Financial Transmission Rights,FTR is a financial instrument that entitles holder to a stream of revenues (or charges) based on the DA hourly energy price differences across the path or shadow price of a flowgate.,Paliza Consulting, LLC. ,17,FTR Characteri

17、stics,MPs will be able to acquire point-to-point (PTP) and flowgate (FGR) transmission rights to hedge congestion charges. PTPs and FGRs will be financial. PTP is a full hedge between source and sink while FGR is a full hedge for a specific constraint only. PTPs will be available in the form of obli

18、gations and options and FGRs will be available as options. Awarded PTPs and FGRs will be simultaneously feasible.,Paliza Consulting, LLC. ,18,Congestion Charge = 100 MWh * ($20-$15) = $500 FTR Credit = 100 MW * ($20-$15) = $500,LMP $20,LMP $15,Example: Delivery with FTR,Paliza Consulting, LLC. ,19,P

19、TP Rights Characteristics,Obligations can have a zero, positive, or negative value. Options can only have a zero or positive value. It is a perfect hedge against congestion costs as long as: Schedule is between specified source and sink. Schedule is equal or less than the FTR amount.,Paliza Consulti

20、ng, LLC. ,20,FGR Rights Characteristics,FGR owner gets paid the constraint shadow price of that flowgate. FGRs are proposed as options and only hedge the specified flowgate. Available as PTDF (monitored element) and OTDF (monitored/contingency pair) flowgates. Place responsibility for assessment of

21、shift factors and the number of FGRs required to hedge a transaction on the market participant.,Paliza Consulting, LLC. ,21,Priorities and FTRs,SMD proposes when transmission is tight, participants with FTRs have scheduling priority. How about curtailment priorities? Current LMP markets do not have

22、this physical characteristic. Many comments have been submitted on this subject.,Paliza Consulting, LLC. ,22,Acquiring FTRs,Allocation Is based on existing contracts. Is a conversion process from physical to financial. FTR Auction - administered by the ITP MPs can purchase “left over” capability. It

23、 may be used as the primary way to assign FTRs. MPs can reconfigure FTRs. Secondary market - bilateral trading ITPs will facilitate the secondary market. FTRs that exist are bought or sold.,Paliza Consulting, LLC. ,23,What Is Missing in the SMD?,From an operations perspective: SMD embraces the goal

24、of seamless markets but no approach is suggested. FERC has taken a significant step forward in developing the SMD but the next step coordination of these markets - is also a very important one.,Paliza Consulting, LLC. ,24,Inter-ITP Coordination,Types of ITP coordination under SMD: LMP market and non

25、market coordination LMP market and other LMP markets Reliability backstop process One stop shopping desired features: Common business practices Common user interface Availability of CRRs that expand several ITPs,Paliza Consulting, LLC. ,25,Transitional Issues,SMD calls for conversion of all transmi

26、ssion service to SMD. However, if grandfather contracts do not convert to the SMD tariff, another level of complexity will be created Will require that ITPs support physical service in all of their markets (RTM, DAM, FTR). Certain special provisions of these grandfather contracts may be difficult to

27、 honor/administer by the ITP under LMP.,Paliza Consulting, LLC. ,26,Transitional Issues,Initial allocation of CRRs May prove to be very contentious specially in places where the system is oversold. Availability of FTR options will add another layer of complexity. Modeling of FTRs in the allocation p

28、rocess needs to be consistent with settlements of these rights.,Paliza Consulting, LLC. ,27,Inter-ITP Coordination Elements,Honor external constraints in the same way as internal constraints are respected. Treatment of resources in a multi-market environment Bidding, control, scheduling, settlement

29、Ancillary services Parallel flow agreement that includes: Definition and calculation of parallel flow Agreement on usage and compensation Convergence of LMP prices at the seams.,Paliza Consulting, LLC. ,28,Reliability Backstop Process,NERC TLR is the reliability backstop process in the eastern inter

32、 a single user interface is a must. Support for CRRs across several ITP regions.,Paliza Consulting, LLC. ,30,The Obvious Fix,Creation of a single market run by a single market operator Single RTM, DAM, and FTR markets Is this feasible over a very large area? Eastern Interconnection MISO-PJM-SPP What

33、 is the criteria for determining the appropriate size of a single market?,Paliza Consulting, LLC. ,31,Managing Seams,Type of seams: Manageable. Unmanageable (e.g. unable to control internal constraints). A couple of factors to consider to manage seams: Proper grouping of constraints & resources. Int

34、ernalize as much loop flow as possible.,Paliza Consulting, LLC. ,32,The Midwest Markets,Dec 2003 is the target date for MISO-SPP market operation. It is a staged project. Functionality to be provided in the first stage is based on RTM, DAM with no SCUC, FTR market, and Market Power Mitigation. Full

35、SCUC and Ancillary Services market will be added in future stages.,Paliza Consulting, LLC. ,33,MISO Markets Initial Functionality,Paliza Consulting, LLC. ,34,The Midwest Markets,Significant challenges: No experience operating as a pool. Many control areas of all sizes. Allocation of transmission rig

36、hts in areas where system is overbooked. Coordination with PJM and other neighboring entities. Resolution of WI and MI hold harmless provisions. Aggressive timeline. MISO-SPP merger needs to be completed.,Paliza Consulting, LLC. ,35,MISO-PJM-SPP Territory,Paliza Consulting, LLC. ,36,A Joint and Comm

37、on Wholesale Energy Market,The goal is to develop a common single wholesale market with a “one-stop shop” that meets the needs of all customers and stakeholders using the electric grid in the 26 states served by them.,Paliza Consulting, LLC. ,37,Paliza Consulting, LLC. ,38,Schedule,May 2003 AEP & DP
