“…In [12,17], the efficiency of multiobjective group search optimizer with adaptive covariance and Lévy flights (MGSO-ACL) algorithm has been verified for the multi-objective optimization problems with two objectives. However, the MGSO-ACL has not been tested on problems with more than three objectives, that is, the MaOPs.…”

“…The dispatch problem of an IES studied in this paper conducts in 1-hour interval [10][11][12]25]. In order to compromise the competing benefits of the electricity network, gas network, and distributed DHCs, the power trade-offs among them are investigated in detail by means of optimizing the selected objectives simultaneously.…”

“…Although [9,12] adopted the multi-objective optimization model to tackle the planning and operation problems of the integrated electricity and gas network, only the costs of the two networks were taken into consideration from the economic point of view. The power system dispatch problem minimizing the emissions and fuel cost simultaneously is referred as environmental/economic dispatch (EED), and it has attracted much attention of researchers to settle this issue [13,14].…”

“…In most of the previous research, only the gas-fired generator has been considered as the linkage between the electricity network and gas network. Reference [12] proposed the model of an integrated energy system (IES) with electricity network, gas network, and district heating and cooling units (DHCs) embedded, in which both the gas-fired generators and DHCs are regarded as the interconnections of the electricity network and gas network. Then a coordinate scheduling strategy was utilized to optimize conflicting benefits of the two networks.…”

This paper develops a many-objective optimization model, which contains objectives representing the interests of the electricity and gas networks, as well as the distributed district heating and cooling units, to coordinate the benefits of all parties participated in the integrated energy system (IES). In order to solve the many-objective optimization model efficiently, an improved objective reduction (IOR) approach is proposed, aiming at acquiring the smallest set of objectives. The IOR approach utilizes the Spearman's rank correlation coefficient to measure the relationship between objectives based on the Pareto-optimal front captured by the multi-objective group search optimizer with adaptive covariance and Lévy flights algorithm, and adopts various strategies to reduce the number of objectives gradually. Simulation studies are conducted on an IES consisting of a modified IEEE 30-bus electricity network and a 15-node gas network. The results show that the many-objective optimization problem is transformed into a bi-objective formulation by the IOR. Furthermore, our approach improves the overall quality of dispatch solutions and alleviates the decision making burden.

“…A general multiple energy carrier power flow model was developed based on nodal power balance, and line losses were calculated as polynomial functions of the corresponding power flow [16]. The nonlinear model of the gas network was formulated in detail containing gas well, gas pipeline, gas compressor, gas loads, and so on [17][18][19]. In [20], a natural gas network system was incorporated in IES, and the gas shift matrix, similar to the generation shift factor in DC power flow model, was formulated to linearize the pipeline flow equation so that the computational efficiency was improved.…”

Hierarchical Energy Management for the MultiEnergy Carriers System with Different Interest Bodies

et al. 2018

Multi-energy carriers system (MECS), in which diverse energy carriers and different energy systems interact together, has drawn the interest of many researchers in recent years. However, the optimal economic operational model of the MECS is a nonlinear, multi-variable, and multi-period problem, of which it is difficult to find the solution because several different energy flows are integrated in the system. To this end, three interest bodies in the MECS were investigated, which included the energy provider, the energy facilitator, and the energy consumer, and a hierarchical optimal economic operation strategy was then presented. A hybrid optimization strategy combining the swarm intelligence algorithm and interior point method was developed taking advantage of the merits of each method. Case studies were conducted to verify the effectiveness of the proposed hierarchical optimal economic operation strategy, whereby demonstrating that the proposed strategy can achieve rational energy allocation and decrease the energy cost in the MECS compared with traditional energy systems.
