Abstract:
Limited by vehicle space, the mobile energy equipment (MEE) has drawbacks such as poor endurance, single energy consumption, and high idle rate. So developing new or improved mobile equipment is urgent. Meanwhile, considering the differences in work modes and network access methods, existing power supply restoration and control strategies for MEE scheduling are difficult to directly apply. Therefore, an energy stored vehicle with soft open point (SOP) (ESV-SOP) and its multi resource collaborative power supply recovery strategy are proposed in this article. Firstly, the working principle of ESV-SOP is explained, and its operating modes under various working conditions are discussed. Secondly, considering the impact of post disaster road conditions on mobile resource scheduling, a method for characterizing mobile resource scheduling paths that takes into account road fees is proposed. Then, a mathematical model and operational constraints for the distribution network and multiple types of resources are established, with the goal of minimizing the total economic cost. A multi resource collaborative power supply recovery strategy considering distributed resource regulation, manual fault repair, contact switch action, and ESV-SOP scheduling is proposed. Finally, numerical examples are carried out in IEEE 33 and IEEE 69 bus distribution networks to verify the progressiveness of ESV-SOP and the effectiveness of the power recovery strategy provided.
