14:30 - 16:00 Advanced design and control solutions for grid integration
Integrating wind power into the electricity market  
Onshore      Offshore    


Room: Montparnasse

Many new issues must be solved in order to integrate large amounts of wind power into energy supply systems. This session will consider how grid code compliance can affect wind power plant design and operation. Wind power plants must be able to tolerate short circuits on the grid, so testing of fault ride-through capabilities of turbines is required; and the design of circuit breakers for HVDC-connected wind farms is a particular issue. The session also considers harmonics caused by wind turbine inverters, and a method for modelling the effect of wind power plants containing multiple DFIG wind turbines is presented.

Learning objectives

​Delegates will be able to:

  • Understand grid code requirements for wind power integration
  • Recognise how wind pant can be designed and operated to comply with grid codes, and the effect on cost of energy
  • Understand new solutions for circuit breakers in HVDC-connected wind farms to deal with grid faults, and testing facilities for wind turbine fault ride-through capabilities
  • Appreciate methodologies for assessing harmonics caused by wind turbine inverters
  • See how symbolic computation can be used to simulate the effect of wind farms comprising DFIG wind turbines

Abstract

Integrating wind power – a further look at its impact on overall LCOE

Introduction

The challenges associated with the grid integration of wind and other renewable power
generation technologies continue to be a major point of discussion across various forums,
committees and conferences. Significant progress has been made with the deployment of
new technology solutions alongside the drafting and enforcement of grid codes. And yet, in
many markets, there is still a perception that the end user must pay an extra premium on
their electricity bill associated with the integration of renewable power.
But what are these grid integration challenges now? And how can we deploy the optimal
solutions to reduce the levelized cost of energy (LCOE) while ensure the quality and stability
of electricity supply essential to keep the lights on?

Approach

LCOE is an assessment of the economic feasibility of an energy source that incorporates
costs over the lifetime of the project such as capital, fuel, and maintenance. While the wind is
essentially free, exploiting wind power requires significant capital expenses that raise its
LCOE, especially in ensuring grid code compliance. ABB has developed a raft of solutions to
design, control and operate wind farms to ensure effective grid integration.

Main body of abstract

This paper highlights some of the possible solutions to design, control and operate wind
farms to facilitate effective grid integration. It starts by showing how it is possible to achieve
grid code compliance in a cost effective way. The paper then presents various control
solutions available at the plant, portfolio or fleet level. It reviews their benefits with respect to
improving the quality of supply and grid code compliance along with their capabilities to
reduce the LCOE through advanced control logics and sensing technologies.
The paper concludes by reviewing another powerful tool to facilitate the integration of wind
power - portfolio wide power management. This employs a supervisory control system to
alleviate power fluctuations caused by variations in wind speeds. It can also integrate other
generation technologies such as hydro, biomass, and/or energy storage. With the right
control logics and strategy, wind power could even provide grid services to system operators.
And the paper will demonstrate how a suitable control strategy can allow wind power to
participate in the ancillary services market.

Conclusion

Reducing the LCOE is a major issue for the effective grid integration of wind power. ABB has
developed a portfolio of solutions for the design, control and operation of wind farms to
facilitate effective grid integration.


Learning objectives
Grid code considerations are a critical element in achieving the optimal LCOE, various
control solutions are now available for the wind turbine plant, portfolio and fleet level to
achieve grid code compliance cost-effectively.
