The aim of this paper is the design and implementation of an advanced model predictive control (MPC) strategy for the management of a wind–solar microgrid (MG) both in the islanded and grid-connected mo.
How can energy storage system capacity configuration and wind-solar storage micro-grid system operation be optimized?
A double-layer optimization model of energy storage system capacity configuration and wind-solar storage micro-grid system operation is established to realize PV, wind power, and load variation configuration and regulate energy storage economic operation.
Simultaneously, wind farms equipped with energy storage systems can improve the wind energy utilization even further by reducing rotary back-up . The combined operation of energy storage and wind power plays an important role in the power system's dispatching operation and wind power consumption .
Do energy storage capacity and wind-solar storage work together?
This paper considers the cooperation of energy storage capacity and the operation of wind-solar storage based on a double-layer optimization model. An Improved Gray Wolf Optimization is used to solve the multi-objective optimization of energy storage capacity and get the optimized configuration operation plan.
How can energy storage improve grid-connection friendliness of wind power?
By installing an energy storage system of appropriate capacity at the wind farm's outlet and utilizing the storage and transfer characteristics of ESS, the influence range of uncertainty can be reduced from the entire power system to the power generation side, which greatly improves the grid-connection friendliness of wind power.
How to optimize wind-solar storage system?
In order to maximize the operation benefit of the wind-solar storage system, the real-time output optimization model of each generation unit in the wind-solar storage system is established in the lower layer. The double-layer optimization model is composed of the objective functions and constraints of the upper and lower levels .
What is a wind-energy storage hybrid power plant?
As a result, a wind-energy storage hybrid power plant, as a kind of combined power generation system, has received a lot of attention. Many Chinese provinces have issued corresponding policies to encourage or require the construction of a certain proportion of energy storage facilities in new wind farms.
