“…In this section, numerous studies that have been performed on the exploitation of microgrids in literature are reviewed. In [9], modeling various types of DRPs is considered in terms of the price elasticity of demand and the idea of customer profit. Besides, the DRPs implementation effect on the operation of grid-associated microgrids is studied.…”

Microgrids are new technologies for integrating renewable energies into power systems. Optimal operation of renewable energy sources in standalone micro-grids is an intensive task due to the continuous variation of their output powers and intermittant nature. This work addresses the optimum operation of an independent microgrid considering the demand response program (DRP). An energy management model with two different scenarios has been proposed to minimize the costs of operation and emissions. Interruptible/curtailable loads are considered in DRPs. Besides, due to the growing concern of the developing efficient optimization methods and algorithms in line with the increasing needs of microgrids, the focus of this study is on using the whale meta-heuristic algorithm for operation management of microgrids. The findings indicate that the whale optimization algorithm outperforms the other known algorithms such as imperialist competitive and genetic algorithms, as well as particle swarm optimization. Furthermore, the results show that the use of DRPS has a significant impact on the costs of operation and emissions.

“…In a grid-connected mode, the MGs-cluster is created by connecting them and the distribution network (Luo et al, 2020). Due to cluster formation and grid-connection, each MG utilizes the local grid resources Ghadi et al, 2019;Mostafa et al, 2020), as well as those of other MGs Gao et al, 2017;Ali et al, 2019;Toutounchi et al, 2019).…”

et al. 2021

Microgrids (MG) cluster are isolated from the utility grid but they have the potential to achieve better techno-economic performance by using joint energy and reserve sharing among MGs. This paper proposes a techno-economic framework for the optimal operation of isolated MGs-cluster by scheduling cooperative energy sharing and real-time reserve sharing for ancillary services based on the cooperative game theory. In the day-ahead scheduling, a coalitional sharing scheme is formulated as an adjustable robust optimization (ARO) problem to optimally schedule the energy and reserves of distributed generators (DGs) and energy storage systems (ESSs), thereby responding to the uncertainties of photovoltaic systems, wind turbines, and loads. These uncertainties are the main reason for power system imbalance which is mitigated by regulating the frequency in real-time and a dynamic droop control process is used to realize the reserves in a distributed manner. This control process is embedded into the ARO problem, which is formulated as an affine ARO problem and then transformed into a deterministic optimization problem that is solved by off-shore solvers Apart from the reduction in the operation cost, the frequency restoration can be improved jointly, resulting in the coupled techno-economic contribution of the MGs in the coalition. The contribution of each MG is quantified using shapely value, a cooperative game approach. Simulations are conducted for a case study with 4 MGs and the results demonstrate the merits of the proposed cooperative scheduling scheme.

In order to make up for the shortcomings of the development of traditional distribution networks, and promote the diversification of energy structure, active distribution network (ADN) came into being. With the large amount of distributed energy resources (DER) connected to the grid, the economic operation evaluation of the active distribution network has been greatly restricted. According to the characteristics of the active distribution network, 7 second-level evaluation indicators such as DER penetration rate are defined in this paper. At the same time, combined with the indicators of the traditional distribution network, a new active distribution network economic operation evaluation index system is constructed, which includes 7 first-level indicators and 21 second-level indicators, and a comprehensive evaluation model based on fuzzy borda method is proposed. This comprehensive evaluation model is put forward due to inconsistent results of evaluation methods, in addition, Kendall-w coefficient is used for the prior consistency test, fuzzy borda method is used for the combination evaluation of different results of several evaluation methods. By considering the difference of evaluation results, the evaluation results are closer to the reality. Finally, the simulation and sensitivity analysis of the last example verify the rationality and effectiveness of the index system and the evaluation model. INDEX TERMS ADN, economic operation, Kendall-w coefficient, fuzzy borda method, combined evaluation.
