End-consumers, as the primary drivers of carbon emissions, are receiving increasing attention for decarbonization of energy systems. Most of the existing studies on carbon pricing overlook the impact of energy consumption behavior of consumers and fail to leverage the potential of demand-sides to achieve greater carbon emission reductions. This paper proposes a low-carbon demand response (LCDR) framework for decarbonization of power-hydrogen integrated energy systems (PH-IESs) and an equitable allocation of carbon responsibility to various types of consumers. A consumer-based carbon pricing strategy with improved marginal carbon intensity is first developed to quantify the impact of the amount and behavior of energy consumption on carbon responsibility and costs. Then, a consumer-based LCDR model is proposed for demand-side energy aggregators (DSEAs) who adjust flexible loads to reduce operation costs and carbon emissions based on the determined carbon price. Finally, a low-carbon operation model is formulated to schedule the PH-IESs considering the responses of DSEAs. To capture renewable uncertainties and reduce decision conservatism, distributionally robust joint chance constraints are established capitalizing on heterogeneous information (i.e., moment, unimodality, and mode skewness). Case studies verify the effectiveness of the proposed LCDR framework.
