Abstract

Abstract: Efficient and clean supply of energy is a top priority for China's development. In order to improve the energy utilization efficiency and renewable energy accommodation, an energy efficiency optimal dispatch model is proposed for terminal energy internet. In view of the multi-energy flow characteristics of terminal energy internet, a new indicator named energy utilization exergy-efficiency is proposed for terminal energy internet, which introduces the concept of exergy and considers the impact of the grid connection and renewable energy access. A corresponding model of energy efficiency optimal dispatch is thus established. The rationality and superiority of the proposed indicator and model are verified by case study. The results show that, energy utilization exergy-efficiency can more accurately reflect the efficient use of energy by terminal energy internet; energy efficiency optimal dispatch can promote energy cascade utilization, energy-saving and emission-reduction, and there is consistency between the results of the proposed dispatch and economic dispatch. So the energy efficiency optimal dispatch can help guide the development of outsourcing electricity prices for terminal energy internet in the incremental distribution network area.

Key words: terminal energy internet, energy efficiency optimal dispatch, energy utilization exergy-efficiency, CCHP, renewable energy resources
