The Impact of Multi-energy Complementary System on the Reliability of Energy Supply of Distribution
2018
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).
