Agent-Based Coordinated Operation Strategy for Active Distribution Network With Distributed Energy Resources

Abstract

With the development of distributed energy resources (DERs) and the increasing flexibility in active distribution networks (ADNs), the economic operation of ADN coordinating both generation and demand sides is required to be studied. In this paper, considering the electricity price response of DER, a coordinated operation strategy for ADN is presented based on a bi-level agent framework. DER agent makes their own response based on the technical operability and economic consideration, while ADN agent will finally coordinate each participant by using the interactive benefit prioritization (IBP) principle. The simulation results indicate that the proposed strategy cannot only reduce the power imbalance, but also improve the economic operation of ADN. Moreover, consumption of renewable energy is ameliorated as well.

Scalable assessment method for agent‐based control in cyber‐physical distribution grids

“…Following the study presented in [6], functionality and scalability are jointly in the focus of the assessment -and not just one of the two characteristics. Often, scalability is not well addressed, since only small use cases of electrical grids with up to 100 nodes or less are studied for a proof of concept [7][8][9][10][11][12][13][14][20][21][22].…”

Research on Distributed Source-Load Interaction Strategy Considering Energy Router-Based Active Distribution Network

“…Thus, the concept of active distribution network (ADN) is proposed. ADN is a type of advanced DN with flexible power flow management system, and can make full use of distributed resources to facilitate integration of distributed generation (DG) into an existing network [3], [4]. In ADN, active energy management such as source-grid-load interaction (SGLI) is expected to solve the adverse effects resulting from the stochastic and volatile output of DG, and achieve a high proportion of distributed energy as well [5].…”

“…To take the situation of forward and reverse power flow and the fairness of line loss allocation into full consideration, a new loss allocation method is proposed. Power losses of P ij and P ij are l ij and l ij respectively and are shown in (4).…”

Distributed Energy Management for Port Power System under False Data Injection Attacks

“…Port energy management is gradually transformed into a distributed management method with the advantages of flexibility, high reliability, and scalability [15][16][17]. A number of studies concerned about energy management have been proposed for power systems, including hierarchical decentralized energy management, multiagent system-based coordinated operation strategy, and hybrid energy management [18][19][20]. To solve the energy management problem of the energy Internet, the work in [18] proposed a completely distributed algorithm, in which each participant can realize the estimation of the optimal energy price and the calculation of the optimal energy output by only interacting with the neighbors.…”
