Dynamic environmental economic and collaborative flexibility dispatch of integrated power, heating and natural gas energy system

Abstract

The integrated power, heat and natural gas energy system (IPHNGES) is of great significance for promoting multi-energy cooperation and complementarity, realizing low-carbon economic operation of energy system, and improving the flexibility and scheduling potential of energy system. It has become an important development direction of energy Internet. Comprehensively considering the diversified interconnection methods of multiple heterogeneous energy systems, a variety of improved equipment models with continuous adjustment capabilities and higher flexibility potential are established on the basis of traditional energy conversion units, and the models are more refined and practical. In this paper, a unified steady-state power flow model considering power, heat and natural gas sub-heterogeneous energy systems is proposed. With the objective of minimizing IPHNGES's carbon emissions and operating economic cost, a dynamic environmental economic and collaborative flexibility dispatch is carried out based on multi-objective fuzzy optimization method. Finally, IPHNGES simulation results demonstrate the effectiveness and feasibility of the proposed model and method.
