With increasing penetration of distributed generators (DG), the uncertainty and intermittence renewable energy has brought new challenges to economic dispatch promotion environment sustainability microgrids. Active loads, especially in electric vehicles (EVs), are thought be an efficient way deal with energy. One most important features EVs is that their demand will vary response electricity price. How determine real-time charging price guide orderly operate uncertain output represents topic for microgrid operator (MGO). To this end, paper formulates optimal pricing robust problem MGO as a Stackelberg game, which upper level minimizes MGO’s cost, while lower cost each EV. In problem, approximate linear relationship between node voltage equivalent load modeled, expression security constraint derived. Using dual optimization theory, model transformed into programming without variables. Then, game mixed integer program by using duality theorem programming. Finally, effectiveness proposed method proved simulation within modified IEEE33-bus system.

In the context of modern power systems, reliance on a single-time-of-use electricity pricing model presents challenges in managing electric vehicle (EV) charging way that can effectively accommodate variable supply and demand patterns, particularly presence wind generation. This often results undesirable peak–valley differences microgrid load profiles. To address this challenge, paper introduces an innovative approach combines time-of-use with flexible energy storage capabilities vehicles. By dynamically adjusting prices implementing tiered carbon system, comprehensive strategy for formulating optimized discharging plans leverage inherent flexibility aims to mitigate fluctuations enhance overall grid stability. The proposed was simulated compared no-incentive single-incentive strategies. indicate peak-to-trough difference reduced by 30.1% 18.6%, respectively, verifying its effectiveness superiority. Additionally, increase user income reduction emissions verify need development EVs tandem clean environmental benefits.
