“…Also, the CTI constraints should be satisfied in designing the optimized protective system [52,53]. As mathematically expressed in (1), the operating time of the BRs should be sufficiently greater than the operating time of the PRs [54,55]. In the shown typical smart grid, it means that the operating time of relays 1 should be greater than the operating time of relay 3 if a fault occurs in the distribution line, connecting Buses 1 and 3, as described in (2).…”

The optimized protective systems for smart grids and microgrids have received much attention in recent years. However, besides other selectivity constraints, less attention has been paid to synchronous generators' stability concerns. The stability challenges are intensified in meshed grids compared to radial configurations. The literature review shows that a knowledge gap exists in introducing a communication-aided protective scheme for meshed smart grids, considering the stability constraints. This study tries to fill such a research gap by proposing an optimal protection system using the communication links between directional overcurrent relays on both sides of protection zones/distribution lines. Assigning the optimum standard characteristics to protective relays is another contribution. The introduced study is applied to the distribution portion of the IEEE 30-bus test system. The proposed method is implemented in DIgSILENT and MATLAB to perform the power system simulations and solve the optimization problem. The comparative test results infer that the proposed communication-aided scheme results in a 49.57% improvement in speed of the protection system, while there is no stability constraint violation compared to conventional communication-free schemes. Test results highlight the advantages of this research to meet the stability constraints of distributed generations and selectivity constraints simultaneously.

“…The production capacity of DFIG and renewable energy systems is an offline decision between each time frame and possible operational locations. The results show that the proposed safety concept prevents erroneous and random motion operations and provides faster home isolation compared to the traditional OC safety concept [5]. To sum up, that wind power development have received extensive attention in academia, but there are few unified analysis and evaluation methods for wind power development and consumption capacity.…”

In recent years, with the depletion of conventional fossil energy, renewable energy such as wind energy has attracted more and more attention. The purpose of this paper is to apply the ecological footprint method to the evaluation and calculation of wind energy development and absorptive capacity, and then to study related major issues. First, through the in-depth analysis of the existing wind energy development and consumption theories, the current factors affecting wind energy development and consumption and the existing wind energy consumption patterns are summarized. Taking the wind farm in province M as an example, the weights of each index of wind power development project and wind power consumption capacity are calculated. The calculation results show that, among the technical factors of wind farm projects in M province, wind resources account for 39%, accounting for the largest proportion, followed by site selection and wind farm technical conditions, accounting for 12% and 3% respectively. According to the calculation results of the ecological footprint calculation method, it is estimated that wind energy can absorb 1547 MWh in summer and 1164 MWh in winter. The technical level of the wind farm is excellent, indicating that the technical level is suitable for the construction of wind farms in M province.
