Transient Synchronous Stability Control for a Wind Solar Gas Energy Storage Integrated Energy Management System Considering Carbon Constraints and Dynamic Characteristics

Abstract

Traditional integrated energy management systems may lack comprehensive scheduling and management strategies for wind, solar and natural gas energy storage. This may lead to imbalanced utilisation of energy and the inability to fully utilise the advantages of various energy sources, thereby affecting the economy and operational efficiency of the system. A transient synchronous stability control method for wind, solar and natural gas energy storage integrated energy management systems considering carbon constraints and dynamic characteristics is proposed. Firstly, with the optimisation objective of system economy, a combined dynamic stability analysis method for photovoltaic panels, wind turbines and gas turbines is proposed based on the carbon constraints and dynamic characteristics distribution of wind, solar, gas and energy storage integrated energy management systems. A comprehensive energy management rule model for wind, solar and natural gas storage is established. This comprehensive energy management rule model can help the system achieve comprehensive scheduling and management of wind, solar and natural gas energy storage, in order to maximise the economic and operational efficiency of the system. Then, the model was analysed based on the characteristics of total fuel consumption and unit fuel price. The operational cost is used to describe the lifecycle control project of the material price management system and a control project is constructed with the goal of integrating the annual total cost of the energy system. Finally, the grid search algorithm is used to find the optimal combination of optimisation variables. This model uses transient synchronous control variables for optimisation and solution, such as system radiation conditions, wind conditions, stepped electricity pricing system loads and equipment parameters. Realise transient synchronous and stable control of the integrated energy management system of wind, light, gas and energy storage. The simulation results show that the WS-G-EMS transient synchronisation control using this method has good stability and excellent performance with good stability and small convergence error.
