IEA Task 50

Work Package 4

Electrical design, control, market, and grid service provision from hybrid power
plants.

This work package focuses on the capability of hybrid power plants for grid service provision and flexibility provision to power systems. The work package is organized characterizing different connection concepts for connecting the assets inside the hybrid power plants. Scoping of hybrid power plants will be performed to identify the roles of hybrid power plants in ancillary service and flexibility provision to power systems. Not only traditional ancillary services such as frequency and voltage services will be considered but also futuristic services (such as fast frequency, damping of power system oscillations, voltage balancing (neg. sequence), damping of harmonics, black start capability) will also be evaluated. This work package in this regard will also gain advantage from WP5; for example, collaboration with IEA Wind Task 25 can provide the specifications for ancillary services for future power systems. This work package will also consider different power management and control principles inside the hybrid power plant such as hierarchical control, distributed control, etc. Furthermore, grid codes, test methods and standardization of hybrid power plant’s capabilities will also be considered in this work package. Task Manager: Aeishwarya Baviskar, DTU.

Activites

• Review – Based on state of art, identify different market opportunities and grid code requirements for ancillary services from hybrid power plants in different countries. Considerations will also be taken for futuristic grid services.

• Grid services and flexibility – Scoping of value of hybrid power plant for different ancillary services provision will be performed. This task will provide recommendations in terms of modelling and control of hybrid power plant assets to provide ancillary services and flexibility to the grid.

• Grid Codes, Tests, and standardization – Recommendations for future grid codes, test methods and standardization of hybrid power plants for different ancillary service provision will be provided.
