1. Thirault France Session 4 – Block 4.4 Barcelona 12-15 May 2003 1 A Dynamic Programming Algorithm for the Design of dispersed generation center adapted to Developing Countries

2. Thirault France Session 4 – Block 4.4 Barcelona 12-15 May 2003 2 Presentation’s context Rural electrification in developing countries, Use of dispersed generation, Optimization of the decentralized generation center, use of a dynamic programing algorithm

3. Thirault France Session 4 – Block 4.4 Barcelona 12-15 May 2003 3 Different types of decentralized generation center Using principaly diesel groups with some renewable energy, Using principaly renewable energy (wind for example) with batteries and/or a diesel group

4. Thirault France Session 4 – Block 4.4 Barcelona 12-15 May 2003 4 Optimization’s example A diesel group (80 kW) and a battery pack (80 kWh) Diesel group ac dc Daily load curve

5. Thirault France Session 4 – Block 4.4 Barcelona 12-15 May 2003 5 Optimization’s objective To minimize the Life Cycle Cost of the system, Different variables –Hourly diesel generation, –Hourly battery capacity. Different constraints

6. Thirault France Session 4 – Block 4.4 Barcelona 12-15 May 2003 6 Result’s of the optimization

7. Thirault France Session 4 – Block 4.4 Barcelona 12-15 May 2003 7 Conclusion Considerable cost gains between different subsystems, Development of a tool for the design of rural decentralized generation subsystem.
