Power System Optimal Dispatch and Transaction Model Considering Renewable Energy Output and Electricity Price Volatility

In order to solve the optimization problem of large-scale renewable energy grid-connected power generation, a scheduling optimization transaction model considering renewable energy output and electricity price fluctuation is proposed. The basic requirements and strategies of renewable energy grid-connected power generation at the present stage are analyzed, and an optimization model aiming at the minimum cost is established for the fluctuation of renewable energy output and electricity price, considering gas turbines, battery energy storage, wind power as the operational constraints of photovoltaic and other units. An optimized transaction model based on the database is established, and the KNN algorithm is used for analysis. Finally, combined with the actual engineering, the application analysis of the model proposed in this paper is carried out, and the validity of the proposed model is illustrated.
