Abstract:
Multi-energy flow calculation is the foundation for integrated energy system analysis and optimal operation. In the context of limited interaction information among network operation entities, a novel recursive electricity-gas-heat multi-energy flow algorithm is proposed. The proposed algorithm is based on the bidirectional transmission of power series coefficients, aims to boost both convergence and computational efficiency. First, the holomorphic embedding energy flow models of electricity, gas, and heat energy systems are established respectively. Second, the recursive solver principle of the holomorphic embedding method in multi-energy flow calculation is analyzed. It notes that the transmission of power series coefficients can be divided into two categories: horizontal transmission and vertical transmission. Therefore, a holomorphic embedding multi-energy flow model that can be solved by bidirectional transmission is established. Subsequently, the recursive relationship for the coefficients of the power series in each holomorphic embedding state quantity is derived. The power series coefficients of each state quantity to be solved are recursively obtained through bidirectional transmission, enabling the joint solution of electricity-gas-heat multi-energy flow. Finally, the results demonstrate the feasibility of the proposed algorithm. The proposed algorithm calculates the multi-energy flow based on a small amount of interaction information with better convergence and computational efficiency. © 2024 Power System Technology Press.
