A pumped storage control system for deploying new energy power generation systems

Abstract

The invention discloses a pumped storage control system for deploying a new energy power generation system. The system includes an environment detection unit that detects environmental factors, the environmental factors include light intensity and wind force; the new energy power generation system includes Photovoltaic power generation system and wind power generation system; it also includes dispatching side devices and pumped storage unit side devices. The invention provides a system for deploying pumped energy storage through new energy. By setting the dispatching side device and the pumped storage unit side device, the interaction between the pumped storage unit and dispatching is realized, not only accepting dispatching instructions, but also Realize emergency self-control, and then be able to realize its own stability in real time, avoiding delays in adjustment opportunities.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a control system capable of using new energy to cooperate with a pumped storage unit to realize stable operation. Background technique [0002] The pumped storage unit is different from the ordinary generator set. It can not only output power as a power source, but also store electricity as a load. The stable operation of the pumped storage unit depends on the coordinated action of the generator and the turbine. Therefore, compared with ordinary generating units, the operating conditions of pumped storage units are more complicated, and it is necessary to consider the output of pumped storage units, that is, the operation of the generator, and the hydraulic control, that is, the operation of the turbine. The condition of the reservoir also needs to be considered. [0003] The control system of the existing pumped storage unit is relatively simple, and there is no comprehensiv...

AI Technical Summary

Problems solved by technology

[0003] The control system of the existing pumped storage unit is relatively simple, and there is no comprehensive consideration of all aspects that restrict the safe and stable operation of the pumped storage unit, resulting in a large discrepancy between the dispatch order and the actual operation. When the power generation command is issued, the unit can no longer generate power, which makes the command invalid and delays the opportunity to adjust the balance of the power grid

[0004] In the prior art, due to the general randomness and instability in the power generation of new energy, the electric energy sent by the new energy is generally stored in the battery, and discharged from the battery to the load when needed, and then the cost of the battery itself is relatively low. High, long-term use will reduce the service life, and waste battery materials will also cause great environmental pollution, while pumped storage mainly uses the attributes of natural resources and will not cause pollution to the environment
