An Innovative Optimal Integration of Wind and Solar Resources for Reliable and Sustainable Power Generation

This work intends to develop a procedural tool that will facilitate the replacement of fossil fuel based generation with the integration of utility scale solar-wind hybrid plants. It will result in a methodology for calculating suitable hybrid plant locations and an optimized plant sizing and energy storage control strategy which will allow for reliable power injection and storage that is capable of meeting the demand of a variable load. Although the separate interconnection of both wind and solar based generation has become common place, the integration of a large scale hybrid generation facility has yet to be achieved. Here, we are focusing on issues such as resource variability, energy storage and power system reliability in order to have hybrid plant supplement conventional generation. The synergistic merging of the two technologies – solar and wind power is being investigated and solutions will be proposed for optimal control and reliability assessment of such hybrid plants.
