Embodiment Construction

[0077] In this embodiment, a wind power hierarchical smoothing system considering demand-side response includes: wind turbines, energy storage devices, load groups participating in demand-side response, wind power forecasting module, load scheduling module, and load optimization module; load group Including: uncontrollable loads and translational loads in controllable loads;

[0078] The wind power prediction module obtains the historical output data of wind turbines and predicts the future output data, so as to establish a mathematical model of time-of-use electricity price;

[0079] The load scheduling module obtains the load parameter information of the shiftable load, and performs hierarchical processing on the shiftable load according to the descending order of the time scale, and obtains N layers of shiftable load curves; denoted as {L 1 , L 2 ,...,L n ,...,L N}; L n Indicates the shiftable load curve of the nth layer; 1≤n≤N; at the same time, obtain the load paramet...

Abstract

The invention discloses a wind power layered smoothing system taking regard of response from a demand side, and a method thereof. The method comprises the following steps: 1) establishing a source-load-storage interactive layered smoothing model including a wind power time-of-use power price mathematical model, a charging and discharging state model for an energy storage device, a load layered optimization wind-power power smoothing model, and an energy storage device charging and discharging state optimization model; and 2) based on a PSO particle swarm optimization algorithm, calculating the models, and obtaining the optimal scheme for translatable load operation and scheduling and for energy storage device charging and discharging. The wind power layered smoothing system taking regard of response from a demand side, and the method thereof enable the load to effectively track a wind turbine generator system to output capacity, can reduce the volatility for outputting wind-power power on a junctor to smooth outputting of the wind-power power and improve the economical efficiency for power purchase in the system for users.

Description

technical field [0001] The invention relates to the technical field of demand-side response, and more specifically relates to an optimization system and method for optimal dispatching of user-side loads, reducing the volatility of large-scale renewable energy accessing a power grid, and maintaining stable operation of the power grid. Background technique [0002] With the continuous development of the world economy, energy and environmental issues have become increasingly prominent, and renewable energy has become an important part of the national energy strategy. The intermittence and volatility of large-scale distributed power generation will have a negative impact on the power quality and stability of the grid. Research shows that user load and energy storage, as an important part of demand-side resources, can effectively participate in the operation optimization of the power grid system and play a vital role in maintaining the safe and stable operation of the power grid....
