Abstract

The invention discloses an energy storage charge and discharge capacity control system based on a wind driven generator. The energy storage charge and discharge capacity control system comprises a monitoring data processing module, an energy storage life estimation module, a system database module, an energy storage capacity distribution module and a control execution module; through monitoring, processing, estimating, capacity allocation, and charging and discharging control, the purpose of reasonably arranging the operation of an energy storage device is achieved; the structure is simple, and the energy storage is automatically selected and controlled by combining the power generation capability of the wind power generation and by means of performing charging and discharging control on the energy storage capacity; and the service time of an energy storage unit is prolonged, and the energy storage cost is lowered.

Description

technical field [0001] The invention relates to an energy storage control system, in particular to a wind power generator-based energy storage charging and discharging capacity control system and method. Background technique [0002] Wind power is currently one of the green and clean energy sources with broad application prospects in the world, and many countries are vigorously developing wind power and other new energy sources. Due to the instability of the wind speed itself, the output power of the wind farm is fluctuating and intermittent. This makes the power supply of grid-connected wind turbines unable to meet the requirements of stability, continuity and adjustability. One solution is to store unstable wind power in energy storage devices and output stable power. On the other hand, when wind power is restricted by the grid to be connected to the grid, the electric energy that cannot be connected to the grid can also be stored in energy storage to reduce power waste....
