Progress

Work developed:

 

18/02 - 20/02 and 23/02 - 25/02

  • Literary review:

    • Technical capabilities of wind turbines;

    • Proof of frequency control provision with wind farms;

    • Forecasting tools of: wind power, day-ahead and balance prices and regulation direction;

    • Bidding in control reserve markets;

  • Study of the decision problem.

 

26/02 - 27/02 and 02/03 - 06/03

  • Writing the state of the art, based on the literary review.

 

09/03 - 12/03 , 17/03 - 20/03 and 23/03 - 27/03

  • Problem formulation (textual and mathematically):

    • defining the objective function;

    • defining how to penalize differences between the contracted and delivered quantities;

    • defining restrictions;

    • defining the risk criterion;

  • Development of a Matlab and an Excel files to test and verify the problem formulation;

 

13/03 - 16/03

  • Price and wind production data gathering and treatment.

 

30/03 - 03/04

  • Implementing on Matlab the function to calculate the revenue given the market bids;

 

06/04 - 10/04

  • Adapting an EPSO algorithm to the program created in order to find the best market bids;

 

13/04 - 17/04

  • Runing the created program in order to gather results for a complete day (24 hours);

  • Correcting bugs found on the code; 

  • Further development of the thesis manuscript;

 

20/04 - 24/04

  • Correcting the created program - reformulating the evalution of bids;

  • Runing the created program in order to gather results for a complete day (24 hours);

 

27/04 - 01/05

  • Creating a second remuneration scheme, in this version the market player only has access to the values of the delivered power;

  • Correcting the created program - reformulating the penalties;

 

04/05 - 08/05

  • Development of the second remuneration scheme;

  • Running the created program for one hour;

 

11/05 - 15/05

  • Further development of the thesis manuscript;

  • Running the created program for 48 hours on both remuneration schemes A and B;

 

18/05 - 22/05

  • Output analysis;

  • Correcting the created program - reformulating the output calculation in each scheme;

 

25/05 - 29/05

  • Running the created program for one hour;

  • Output analysis;

 

01/06 - 05/06

  • Case study from the Iberian Market;

  • Application of the developed algorithm to an Iberian Wind Farm.

  • Assessment of results;

 

08/06 - 12/06

  • Corrections on the developed program - reformulating each remuneration scheme;

  • Assessment of results from the case study;

 

15/06 - 19/06

  • Writing a first version of the final document;

 

22/06 - 26/06

29/06

  • Delivery of the final document;

Participation of Wind Generation in  Balancing Reserve Markets

Meetings and reports: 

 

27/02 - Meeting with supervisor from INESC TEC.

  • first contact with the problem formulation.

 

 

 

 

06/03 - Meeting with supervisors from INESC TEC and FEUP

  • internship progress;

  • planning the next weeks;

  • defining the work scope: only day-ahead electrical energy and day-ahead balancing reserve markets will be considered.

 

 

 

 

17/03  - Meeting with supervisor from INESC TEC.

  • Discussing the problem formulation.

 

 

 

 

20/03 - Meeting with supervisor from INESC TEC.

  • Discussing the problem formulation.

 

 

 

 

06/04 - Meeting with supervisor from INESC TEC.

  • It was decided that an Evolutionary Programing algorithm (EPSO) will be used in this work. 

 

 

 

 

13/04 - Meeting with supervisor from INESC TEC.

  • Discussing the penalizations that the producers will suffer for not delivering the energy and the power contracted in the day ahead market.

  • Discussing the implemented program.  

 

 

 

 

21/04 - Meeting with supervisor from INESC TEC.

  • Discussing two ways of paying for the produced energy: one where the grid operator can estimate the wind generation and knows how much energy is delivered; another where the operator only knows the qauntity of electrical energy delivered. 

 

 

 

 

28/04 - Meeting  with supervisors from INESC TEC and FEUP.

  • Presenting the work progress.

  • Disussing how to evalute each bid depending on how outcomes are created.

 

 

 

 

08/05 - Meeting  with supervisor from INESC TEC.

  • Discussing updates done to the Matlab code.

  • It was decided that the program would be run in both remuneration schemes with a maximization of the expected utility function and with a CVaR5%.

 

 

 

 

29/05 - Meeting  with supervisor from INESC TEC.

  • Presenting the work progress.

  • Discussion and analysis of the results obtained for 48 hours.

 

 

 

02/06 - 05/06 Meetings  with supervisor from FEUP.

  • Validation of the correctness of the developed algorithm.

  • It was decided that in order to identify possible problems with the implemented code, it would be best if the uncertainty was set aside.

 

 

 

 

11/06 - Meeting  with supervisor from INESC TEC.

  • Discussion of the calculation of the revenue in each remuneration scheme.

  • It was decided that both remuneration schemes should be analysed and debugged.
