Guangzhi Yin

Guangzhi is a PhD stu­dent in Energy Sys­tems Analy­sis at Tsinghua Uni­ver­sity.  He has bachelor’s degrees in Elec­tri­cal Engi­neer­ing and in Man­age­ment from Tsinghua Uni­ver­sity.  He has been a vis­it­ing stu­dent at the Uni­ver­sity of Bath and at the Israel Insti­tute of Technology.

His work is focused on the role of car­bon pric­ing and renew­able energy deploy­ment in China.

Guangzhi will be a vis­it­ing stu­dent at RAEL from Octo­ber 2019– July 2020.

 Cur­rent posi­tion:

Ph.D stu­dent in Elec­tri­cal Engi­neer­ing, Tsinghua University.

Jiang, Kelly

As an under­grad­u­ate Kelly was invited to work as a GSR to com­pile data on decen­tral­ized renew­able energy (DRE) in part­ner­ship with Power for All (P4All) as part of a larger effort to research and to build the case for uni­ver­sal elec­tric­ity access by 2025 through dis­trib­uted renew­able energy.  In this project Kelly is work­ing with Dr. Rebekah Shirley and Pro­fes­sor Dan Kam­men of UC Berke­ley Energy and Resources Group.

In the Spring of 2018 Kelly is also a Vis­it­ing Stu­dent and mini-​​grid research stu­dent at the State Key Lab­o­ra­tory of Trans­mis­sion Equip­ment and Sys­tem Secu­rity and New Tech­nol­ogy at Chongqing Uni­ver­sity where she is super­vised by Pro­fes­sor Minyou Chen of the School of Elec­tri­cal Engineering.

Power system balancing for deep decarbonization of the electricity sector

We explore the oper­a­tions, bal­anc­ing require­ments, and costs of the West­ern Elec­tric­ity Coor­di­nat­ing Coun­cil power sys­tem under a strin­gent green­house gas emis­sion reduc­tion tar­get. We include sen­si­tiv­i­ties for tech­nol­ogy costs and avail­abil­ity, fuel prices and emis­sions, and demand pro­file. Meet­ing an emis­sions tar­get of 85% below 1990 lev­els is fea­si­ble across a range of assump­tions, but the cost of achiev­ing the goal and the tech­nol­ogy mix are uncer­tain. Deploy­ment of solar pho­to­voltaics is the main dri­ver of stor­age deploy­ment: the diur­nal peri­od­ic­ity of solar energy avail­abil­ity results in oppor­tu­ni­ties for daily arbi­trage that stor­age tech­nolo­gies with sev­eral hours of dura­tion are well suited to pro­vide. Wind out­put exhibits sea­sonal vari­a­tions and requires stor­age with a large energy sub­com­po­nent to avoid cur­tail­ment. The com­bi­na­tion of low-​​cost solar tech­nol­ogy and advanced bat­tery tech­nol­ogy can pro­vide sub­stan­tial sav­ings through 2050, greatly mit­i­gat­ing the cost of cli­mate change mit­i­ga­tion. Pol­icy goals for stor­age deploy­ment should be based on the func­tion stor­age will play on the grid and there­fore incor­po­rate both the power rat­ing and dura­tion of the stor­age sys­tem. These goals should be set as part of over­all port­fo­lio devel­op­ment, as sys­tem flex­i­bil­ity needs will vary with the grid mix.

Kittner, Noah

Noah Kit­tner is now a Pro­fes­sor in both City and Regional Plan­ning, and Global Pub­lic Health at the Uni­ver­sity of North Car­olina, Chapel Hill.

Noah Kit­tner was a PhD stu­dent in the Energy and Resources Group at UC Berke­ley and researcher in the Renew­able and Appro­pri­ate Energy Lab­o­ra­tory. After grad­u­at­ing with a BS in Envi­ron­men­tal Sci­ence from UNC-​​Chapel Hill (high­est hon­ors), Noah was a Ful­bright Fel­low at the Joint Grad­u­ate School for Energy and Envi­ron­ment in Bangkok, Thai­land research­ing tech­ni­cal and pol­icy aspects of solar elec­tric­ity and sus­tain­abil­ity assess­ment. Recently, he co-​​authored a Thai Solar PV Roadmap with col­leagues at Chu­la­longkorn University.

He has worked on renew­able energy issues in a vari­ety of con­texts, includ­ing mea­sur­ing land use change and bio­mass fuel uses in west­ern Uganda, installing solar pan­els in Mex­ico, and elec­tric­ity grid mod­el­ing in Kosovo. He is sup­ported through the Berke­ley Cen­ter for Green Chem­istry as a SAGE-​​IGERT fel­low, National Sci­ence Foun­da­tion as a Grad­u­ate Research Fel­low, USAID, and has won an award from the National Go Solar Foun­da­tion for his work on solar photovoltaics.
