Embodiment Construction

[0027] The present invention relates to a method for allowing the grid energy management system (EMS) to call the currently available active power strain in the wind power plant control system to help the EMS automatic generation control (AGC) to control the grid parameters under specific conditions.

[0028] figure 1 A simple illustration of the prior art method used for AGC is shown in. The main goal of AGC is to maintain frequency and power exchange between control areas by increasing and decreasing the power output of selected generating units. AGC achieves this by calculating the area control error (ACE) with two components. The first component of ACE is the difference between the planned frequency and the actual frequency, multiplied by the appropriate gain. The second component is the difference between the planned power exchange and the actual power exchange, multiplied by the appropriate gain. The ACE in MW is then allocated to selected power generation units for implem...

Abstract

An automatic generation control (AGC) augmentation system and method for wind power plant integration for controlling the power contribution to a grid by the wind plant is disclosed that provides for the calculation of the area control error (ACE) by actively communicating to the wind plant ramp rate limits and curtailment requests contributing to the ACE calculation. The augmented control of the ACE minimizes the amount of lost energy production by the wind plant.

Description

Technical field [0001] The present invention generally relates to wind power generation, and more specifically, to a system and method for two-way and / or one-way communication between a wind power plant control system and an energy management system to improve grid operation. Background technique [0002] Generally, a wind power generation system includes a wind power plant with multiple wind turbine generators that provide power to the grid. The aggregate power output of a wind power plant is greatly affected by wind conditions on each wind turbine generator. Grid operators usually have other power resources, such as thermal power plants, to balance power generation and consumption, so as to adapt to changes in wind conditions during intermittent wind conditions. Thermal power plants may include, for example, coal and gas-fired power plants. Power fluctuations in wind farms caused by wind gusts or low-speed wind conditions are usually handled by grid operators by adjusting the p...
