Real-time energy management in a community energy internet with CHP and PV prosumers considering the CVaR values

摘要

This paper puts forward a real-time energy management model for the community Energy Internet (CEI) based on the demand side response. The community Energy Internet consists of CHP system and PV prosumers considering automatic demand response abilities. Firstly, the structure and trading mode of the CEI are introduced. Secondly, the energy management optimization model is proposed considering the stochastic characteristics of the parameters in the CEI, and the objectives consider the costs of all periods and the CVaR value in the future periods. Thirdly, a multi-scenario determination method based on probability distribution of prediction error is also proposed. In the end, the validity of the proposed model is verified from the aspects of optimizing system net load characteristic and prosumers' costs, etc., through the case study.
