Hydroelectric Power Plants

The structure of hydraulic structures of power and water management systems includes gates for various purposes, which allow you to regulate and distribute the flow of water in channels and waterworks. Existing gate designs do not provide for the possibility of generating electricity from the water energy of the stream passing through them. In order to convert the hydraulic energy of water passing through the gates into electrical energy a new patented design of the gate is proposed which allows using micro-hydroelectric power plants with a Banki turbine to make more rational use of the hydro resources of energy and water management systems. The proposed design solves the problem of expanding the functionality of the gate and increasing the efficiency of micro-hydroelectric power plants with a reduction in its cost. Areas of application of the new design for the combined use of micro-hydroelectric power plants and hydraulic gates at hydroelectric power systems are also proposed. The technique for determining the technical and economic parameters of micro-hydroelectric power plants installed on flat gates of hydraulic structures is given, and theoretical calculations are performed, which showed that the higher the capacity of micro-hydroelectric power plants, the shorter its payback period.

Battery Energy

A mathematical model of frequency and power regulation in power systems with large wind power plants (WPPs), hydroelectric power plants (HPPs), and battery energy storage systems (BESSs) was developed. Using this model, we carried out a complex of studies over a wide range of changes in the power of HPPs, BESSs, and their proportions. Options are considered when HPP and BESS work separately. The conditions under which HPPs and BESSs provide a stable operation of the power system, working separately with satisfying the requirements to frequency deviation in the integrated power system of Ukraine and in the ENTSO-E energy system of the European Union are determined. A series of calculations for the joint use of HPPs and BESSs was carried out, and, as a result, recommendations were formulated on the conditions for joint operation of HPPs and BESSs.
