IEEE Power & Energy Society Technical Webinar Series
Energy Integration Assessment of Renewable-Dominated Regions Based on Stochastic Co-Optimization of G,T and Probabilistic Reserves
A South American Case Study
22 March 2018 • 10:00 am Eastern
Presented by Ricardo Cunha Perez, Operation and Planning specialist, PSR SOLUÇÕES E CONSULTORIA EM ENERGIA LTDA
One of the most effective ways of managing the variability of renewable sources is through the portfolio effect of interconnecting regions with diverse production patterns. The economic assessment of these new regional interconnections requires the following enhancements of planning and operation analytical tools: (i) probabilistic simulations of regional system operation with hourly resolution; (ii) stochastic modeling of the spatial dependence of inflows and wind; (iii) calculation of probabilistic generation reserves; and (iv) because renewables usually affect the countries’ power flow patterns in a significant way, it becomes necessary to carry out integrated (co-optimized) generation, transmission and generation reserve planning studies.
The proposed IEEE PES Webinar includes: (a) description of the new multistage stochastic optimization methodologies for planning (Benders-based joint generation-transmission-probabilistic reserve) and operation (SDDP-based multistage G&T stochastic optimization with hourly resolution, including unit commitment and ramping); (b) description of the analytical schemes for evaluating multi-country probabilistic reserve sharing and other interconnection benefits; and (c) presentation of the recent South American interconnection study, sponsored by the Inter-American Development Bank (IADB), which includes nine countries with a 350 GW capacity (planned for 2036), 6-thousand node HV network and a surface area similar to the European Union (or the USA).
Ricardo Cunha Perez has a B.Sc. Degree in Electrical Engineering with an emphasis in Power Systems from Itajubá Federal University and earned his Master's Degree (M.Sc.) in the fields of Electrical Engineering and Optimization by the Rio de Janeiro Federal University. Mr. Perez has been working for PSR since 2009 as a member of the generation & transmission consulting group; responsible for many studies, including the development of a model for power transmission expansion planning used by the WECC in US. Mr. Perez works with the following models: (i) OPTGEN (for optimizing the expansion of generation systems and regional interconnections), (ii) NETPLAN (for optimizing the transmission system expansion) and (iii) the dispatch model SDDP used in more than 60 countries.
