Obiettivo
Objectives
The overall project objective is to identify and analyse methods and technologies for making it viable to utilise more of the wind potential in remote areas. A power control concept for wind turbines which will even out the power fluctuations and make it possible to increase the wind energy penetration will be developed. The main options are to combine wind power with a pumped hydro power storage or with an AC/DC converter and battery storage. The AC/DC converter can either be an "add-on" type or it can be designed as an integrated part of a variable speed wind turbine. Combining wind power with the power control concept makes wind power more firm and possible to connect to weaker grids. When the power control concept is developed, the expectation is that for certain wind power installations, the cost of the power control may be paid back as added wind power capacity value and saved grid reinforcement costs.
Technical Approach
The project comprises concept development, prototype testing and case studies. The concept is developed by applying existing simulation models. To gain actual hardware experience a 50 kW, 30 kWh "add-on" power control prototype is being developed by ABB (NO) and will be tested throughout the project period at the Test Station for Wind Turbines, Risø (DK). The test programme includes performance assessment and monitoring of operating conditions under real life conditions and for various control strategies.
Case studies will be conducted for Madeira (PT) and County Donegal (IE). Both areas have favourable wind conditions but limited grid capacity for significant utilisation of wind power. The case studies analyse and suggest solutions for efficient use of wind energy in the power system by applying the power control system.
Expected Achievements and Exploitation
The project's measurable objectives comprise:
- Detailed power control concept design and operation suggestions. - Installation and real life testing of a prototype add-on PQ power controller.
- Computer models suitable for steady state and dynamic analyses of the power control concept.
- Analyses and evaluation of the concepts based on computer simulations. - Assessment of the market potential.
- Case study analysis including suggestions for financing and implementation of wind power in combination with the optimal power control concept at Madeira (PT) and County Donegal (IE).
Project results will be presented at international conferences. Follow up demonstration projects utilising the power control concept are anticipated.
