Abstract

This paper studies the scenario of multi-energy complementary system accessing medium-voltage distribution network, and quantitatively evaluates the impact of multi-energy complementary system (M-E) on the reliability of energy supply of medium-voltage distribution network (DN). Considering that M-E integrates a variety of energy coupling components with energy conversion functions, this undoubtedly greatly increases the reliability of energy supply. In this paper, the connotation of energy supply reliability is extended from a single grid to a thermo-electric coupling network, and the influence of network operation constraints formed by coupling on solving energy flow is fully considered. Based on the network operation constraints of the electro-thermal-gas coupling network, the cogeneration unit is used as the coupling node, and finally the reliability level under different wiring modes when accessing M-E is quantified. The results show that the M-E has a significant improvement in the reliability of the integrated energy system (IES).

多能互补系统对配电网供电可靠性的影响

本文研究了多能互补系统接入中压配电网的情景，定量评价了多能互补系统(M-E)对中压配电网供电可靠性的影响。考虑到M-E集成了多种具有能量转换功能的能量耦合组件，这无疑大大提高了能源供应的可靠性。本文将供电可靠性的内涵从单个电网扩展到热电耦合网络，并充分考虑了耦合形成的网络运行约束对求解能量流的影响。基于电-热-气耦合网络的网络运行约束，采用热电联产机组作为耦合节点，最终量化了接入M-E时不同接线方式下的可靠性水平。结果表明，该方案对综合能源系统(IES)的可靠性有显著提高。
