2 01 Connection studies peculiarities about crowdfunded distributed PV SMAP, in keeping with «Centrales Villageoises» The «Centrales Villageoises» are local compagnies which develop renewable energies in a territory combining citizens, local government and local actors. But, from a certain amount of renewable energy integration, it s necessary to plan to do electricity network reinforcements. Reinforcement financial costs could impact grid investments and photovoltaic projects (SAS CVRC for example). SMAP is the first smart grid demonstrator minimising reinforcement cost combining the different actors of the system. 2

3 01 Connection studies peculiarities about crowdfunded distributed PV SMAP partners from diverse horizons Associations University 10 partners Compagnies Federation Town Hall Financing : 40% FEDER European fund (on average), 60% self financing from project partners Total = 850 k 3

4 01 Connection studies peculiarities about crowdfunded distributed PV A replicable project focus on Les Haies village Area of SMAP 1 municipality 2 LES HAIES Area of TEPCV* 3 France Lyon 772 inhabitants Photovoltaic «Centrales villageoise» = 76 kw Integrated in a TEPCV* project 86 municipalities form the TEPCV* «Pilat Park Naturel St Etienne Conurbation» Lyon, a very dynamic region with a lot of demonstrator projects 4

5 Smart grid continuity on low voltage network Generation Further measures confirming potential constraints Network already smart (Regional management agency, DEIE, HTA generators) Continuation of Enedis experimentation on voltage regulation (based on smart meters) Transportation (RTE) Distribution Smart meter, the first component of Smart Grids Suppliers Photovoltaic Wind turbine Electric Vehicle Energy control 5

6 01 02 Further measures confirming potential constraints Impact of PV generation on LV grid 6

7 Voltage (V) Generation (Wh) Further measures confirming potential constraints Voltage variation according to PV generation Strong dependance between PV generation and voltage owing to low volume of consumers on the network. Generation site at the end of the line Some voltage values upper or equal to 253 V (in keeping with EN norm) : : :00 Tension Limite Production LES HAIES 7

8 Simulations evaluating the margins and potential future power grid weaknesses 04 Context of the simulation One thesis on the «Study of different innovations to facilitate the massive integration of PV generation on the electricity distribution grid, in a rural area». Content : Presentation of this work + writting of an article: CIRED (Glasgow, June 2017) Phase balancing. Inverter non-centralized control: Each inverter control its power injected on the grid. Inverter centralized control: A concentrator commands all the inverters thanks to voltage data (3 methods). Scenarios translation: Transcription of ««Solar Energy Family» contest. On load tap changer. Taking into consideration of the PV site orientations. 8

9 Simulations evaluating the margins and potential future power grid weaknesses 04 Solutions tested: Local & Centralized Control 1 Active/Reactive Power Control following a voltage droop function Hypothesis: Addition of 3-12 kwc PV plants on end of line Other assumptions: Similar to Enedis dimensioning studies 2 One simple method tested on site & two advanced methods developed by the Grenoble Electrical Engineering laboratory. 9

10 An organisation view with 3 main dimensions Facilitate renewable energy development in rural area by testing innovate solutions which could have an influence on smart grid industrialization methodology Network dimension: A «3D» project Have a better understanding of the network, with smart equipment Better forecast renewable energies development on the network Drive the network in accordance with local constraints Understand link costs Community dimension: Balance consumption flows and local electricity generation Raise awareness among the population Territory dimension: Solutions tested to achieve better PV integration Assist territories (Municipalities community, TEPCV) to better plan renewable energies development to reach their energetic goals 10

11 Solutions tested to achieve better PV integration Some concret examples of achievements Data monitoring web portal Behavioral achievements «Solar Energy Family» contest Transformer On load tap changer Technical achievements Inverters control 11

12 Solutions tested to achieve better PV integration Technical structure for LV regulation 12

13 Inverters control Control based on Smart meter s data Solutions tested to achieve better PV integration Three-phase inverter Cluster controller Control via active power Control via reactive power Q according to P tan(phi) regulation Q according to U Q=f(U) régulation 13

14 Transformer On Load Tap Changer SMAP characteristics Solutions tested to achieve better PV integration Control based on Smart meter s data Distribution substation Tap change (High Voltage) Voltage is stabilizing around set value (235V) Tap change (Low Voltage) 14

15 Conclusion and possibilities SMAP, a concrete and innovative project. A considerable work to put consumer at the heart of the project. An undergoing project (end around October 2018). OLTC 15
