Low-carbon economic dispatch of electricity-gas systems

A reasonable dispatch strategy is of significance to meet and balance the operation economy, carbon emission and operation risk requirements for energy systems. A low-carbon economic dispatch model for electricity-gas systems is proposed, in which the carbon capture systems (CCS), carbon emission trading (CET), demand response (DR) and renewable generation are considered. The impacts of different low-carbon technologies on system economy and carbon emission are investigated. To manage the risk caused by uncertain renewable generation and CET price, the low-carbon economic dispatch problem is formulated as a risk-constrained two-stage stochastic dispatch model based on the chance-constrained programming (CCP). A predefined confidence level is introduced to control the loss of load risk and the transmission line overload risk in the proposed model. Case studies demonstrate the feasibility and effectiveness of the proposed models. (c) 2021 Elsevier Ltd. All rights reserved.
