Advanced pv/wind hybrid plants

Objective

OBJECTIVES AND DELIVERABLES:
Objectives: The objective of the project is to standardize and facilitate the design of hybrid systems. The aimed configuration will further improve the efficiency of hybrid systems while reducing the cost at the same time. This is achieved by using a central power conditioning unit, i.e. an innovative self-commutated bi-directional inverter. The increased efficiency will save fuel in the back-up diesel generator.
The bi-directional inverter will incorporate the following features: * mpp-tracking for matching of the solar generator
* battery management
* stabilization of the wind generator AC output
* compensation for unsteady loading
* excitation control of wind generator
* programmable system management
Data monitoring at the pilot plant will show the improvement in efficiency and the cost reduction achieved by this advanced hybrid system concept. Future hybrid systems will benefit from the results achieved since a standardised and easy hybrid system design with the bi-directional inverter as universal central unit will ensure a wider dissemination of hybrid plants.

The deliverables are :
* Material pilot plant
* Bi-directional inverter samples for laboratory and pilot plant * Wind generator simulation
* PV field tester for solar generator monitoring


BRIEF DESCRIPTION OF THE RESEARCH PROJECT: ADVANCED PV/WIND HYBRID PLANTS
Renewable energy sources like the sun and wind are not supplying constant power. When combining solar energy with wind energy a more continuous supply is achieved since the two energy sources are complementing one another. A diesel generator usually serves as back-up for periods with higher power demand from the loads than available from sun and wind. In this project the system uses a central power conditioning unit, i.e. an innovative self-commutated bi-directional inverter, expected to improve the efficiency and to reduce the cost. Programmable logic will allow flexibility in the system management. The new design will:
* save additional charge controller for PV generator
* generate and stabilize a stand-alone grid without wind or dieselgenerator * eliminate ac-dc-ac conversion of wind generator output
* eliminate ac-dc-ac conversion of diesel generator output
* incorporate the complete system management The R&D work on the self-commutated bidirectional inverter will be supported by solar generator and wind generator hardware simulation in the laboratory. The laboratory work will be complemented by the installation of a pilot plant in an appropriate site on a North Sea island with the advanced hybrid system concept for long-term data acquisition.
