Design and Implementation of Renewable Energy Power System with Peak Load Regulation

The objectives of this project is to design and implement renewable energy power system to comply with our national saving energy and reducing CO2 policies, to regulate peak load for user, to promote utility rate of renewable energy, to establish and help promote the renewable energy demonstration system and to incubate and educate the smart micro-grid applications oriented engineers. In the research, the renewable power system, which includes output voltage type and output current type of output terminal in solar cell DC/DC converter connected in strings, can adopt constant power method to overcome the power losses of solar cell with shading. Furthermore, we develop a DC/DC converter, which possesses maximum power point tracking (MPPT), charging and battery energy regulation performances to increase utility rate of solar cell and battery and to reduce volume and cost due to multi-converter adopted in the power system. In the proposed circuit topology, power line communication and display system are introduced into power system to detect and monitor. The project will last for three years. In the first year, we will focus on mapping out a plan to implement solar cell DC/DC converter output connected in strings with constant power algorithm. In the second year, we will focus on developing power system with MPPT, charging and battery energy regulation performances. In the third year. We will develop power system with power line communication and power management system and integrate the other sub-projects. Moreover, we will establish a technical platform for further research and conduct system commercialization. In this research project, the designed system is highly innovative and feasible. It is relatively competitive because the renewable energy power system adopts power processing technology and is operated at high frequency to reduce volume and increase conversion efficiency. Moreover, it facilitates to implement module and to maintain them. Our research group has already accumulated the design experience of renewable energy power system for many years. Furthermore, we have also verified the feasibility of MPPT chip made by our research group. Based on above experiences, we strongly believe that we are able to fulfill the goals of this project. In particular, this research is an integrated project of a cross-field research. We hope not only to encourage the cross-field integration in Taiwan, but to incubate the cross-field integration researcher by executing this project. It is worth of dedicating in putting long-term effort to them.
