“…As a solution, the use of flexibility sources like ESS and EV along with RES is suggested [24]. In addition, the operation of CHP in the presence of RES will reduce the flexibility of the heating section of the hub [14,22]. Following this, the boiler and TSS are used as sources of flexibility in the thermal part of the hub [14,22].…”

As another point, this paper assumes that CHP, ESS, and EVs are also capable of controlling reactive power, but RESs produce only active power according to IEEE 1547 [24].…”

“…Also, a multistep approach is used in [21] to model the large-scale energy hub operation. e economic dispatching model of the hub considering minimization of the hub cost is presented in [22]. Besides, some research expresses a market model for hubs, such as in [23], where the day-ahead (DA) electrical energy market method is used for grid-connected hubs, including RESs, an electrical storage system (ESS), and CHP.…”

Also, in most research such as [14][15][16][17][18][19][20][21][22][25][26][27][28][29], the operation model of hubs has been considered, while considering the model of the energy market can obtain a suitable financial benefit for it, and this is also the case that has rarely been addressed [23,24].

In order to increase energy efficiency, the energy hub is considered as a form of aggregator and coordinator of various resources and storage. With the optimal performance of resources and storage generators based on a proper energy management system, it is expected that hubs can gain financial benefits from energy markets and ancillary services. So, the paper presents the participation of networked energy hubs in day-ahead (DA) reserve regulation and energy markets, where the hub operator incorporates a coordinated energy management (CEM) strategy to manage power sources and energy storage devices within the hub. Hence, this problem maximizes the total profit of hubs in the DA energy and up and down reserve markets. Also, the problem is constrained by optimal power flow (OPF) constraints in gas, electricity, and thermal networks, reserve limits, and hub constraints, including the model of the combined heat and power (CHP), renewable energy source (RES), electrical/thermal storage, parking lots of electric vehicles (EVs), and boiler. Following that, a linear format is obtained for the nonlinear equation using traditional linearization methods so that an optimal solution is found in less time considering less computational error. Eventually, a standard case system is used to test the strategy, and thus, the capabilities of the approach are investigated. The obtained findings validate the potential of the proposed design in enhancing the economic situation of power sources and storage in hub form, which can enhance operation indices by optimal management of the hub so that the energy management of resources and storage in the form of a hub based on CEM compared to their independent management plan has been able to increase the profit of these elements in energy and up and down reserve markets by about 17%, 28%, and 15%, respectively. Regarding technical indices of energy networks, the proposed scheme by creating low energy losses in the gas network and providing pressure drop, overvoltage, and overtemperature within their permissible limits succeeded in reducing the energy losses in electricity and heat networks by about 83% and 38%, respectively, compared to power flow studies. Also, in these conditions, it has reduced the maximum voltage and temperature drop by 45% and 39%, respectively.

Hence, the configuration of IES is an important issue.…”

The peak-valley difference of power grid will be enlarged significantly with the increasing number of integrated energy systems (IESs) connecting to power grids, which may cause a high operation cost and voltage violations. This study proposes an IES configuration method considering the peak-valley difference of the tie line between IES and power grid. An optimal configuration model of IES is established, which takes the sum of the annual operating cost of the power grid and annual cost of IES as objectives, while the tie line transmission power between IES and power grid are considered as constraints. The elite energy reserve genetic algorithm and branch and bound method are used to solve the proposed model, while the optimal power flow is used to calculate the grid operation cost under a given transmission power of the tie line. The simulation results of an improved IEEE30 node system verify the validity of the proposed method.
