However, limitations exist in the frequency support capability of a hydro turbine. First, the maximum opening/closing speed of the wicket gate is limited, especially when the upper reservoir water level is low . This limits the ramp rate for fast frequency regulation. ... ...
All hydropower units providing FCR-N react to a frequency deviation by changing their active power output according to (5.8). If the frequency decreases, the power output increases and vice versa. As was introduced, the entire FCR-N capacity in the Nordics will be modelled with one lumped HPP.
In the Hydro Recharge HBHS, the HPP is controlling the state of charge of the BESS during operation, giving the architecture its name. The HBHS model is thus composed of a single HPP and a BESS model, with the already defined parameters.
This paper presents a novel method of hydro power plant operation, based on the control of the injectors’ or wicked gates opening time as a function of the upper reservoir level. In this way, a faster power injection, depending on the current water level on the upper reservoir, could be achieved.
Due to its higher price and effect on frequency quality, FCR-N is taken as the frequency regulation product of choice for the HBHS. With the HBHS product and market identified, the influence of market dynamics is disregarded in further work, in order to limit its complexity.
Historically, hydropower was used as a source of baseload generation for electric power, but now it is increasingly used for grid balancing. Among dispatchable renewable energy sources, hydropower plants are the most often used , achieving up to 15 s response times for 90% of the total power response.
