Gepubliceerd in: Variability and Predictability of Large-Scale Wind Energy in the Netherlands, 259, 288, 978-953-7619-81-7, Wind Power.

This chapter presents in a national context energy balancing requirements due to the variability and the limited predictability of wind energy in the thermal energy system of the Netherlands. In addition options to reduce these requirements are discussed. To this end 7.8 GW of wind power capacity in a system with 35 GW of total capacity is considered. The balancing requirements due to the cross-border flow of wind energy (export of domestic wind energy or import of foreign wind energy) however are not covered as these require an international context (ETSO, 2008). In addition the potential benefits of an intra-day market are not explored.

This chapter is organized as follows. First, section 2 presents various scenarios for wind and other energy capacity in the Netherlands, and introduces the structure of the Dutch electricity market. Next, section 3 gives a short overview of studies which addressed balancing energy reduction options in the contexts of the electricity markets in Denmark, Germany and Spain. Section 4 continues with the modeling of wind variability and wind predictability and its relevance to wind energy integration. Sections 5 and 6 then present the balancing energy requirements due to wind variability and limited wind predictability. Subsequently, section 7 discusses options to reduce the extra balancing energy requirements, which options include short-term forecast updates, aggregation, pumped storage, compressed air energy storage, fast start-up units, inverse offshore pump accumulation system, and wind farm shut-down strategies. Finally, section 8 summarizes the results.
