“…To sum up, it is important to say that the stochastic analysis and uncertainty modeling are essential to be considered in the P2P energy market in order to bring an accuracy consensus solution for each participant. 21) and (23), respectively. In contrast to the tidal unit whose uncertainty model led an increased generated power, there is a marked decline in the power generated by WT in the stochastic framework due to the generation-demand balance.…”

“…With the growing concern over the air pollutions in recent years, the renewable energy sources could attain a brighter and more effective role in the power grids [22][23]. The clean nature, high accessibility at different regions and local power generation too close to the end users are some of the most significant features of these sources which could support their role with higher penetration compared to the conventional fossil fuel based DGs.…”

“…The renewable energy sources (RESs) have brought many promising benefits to the power systems in terms of loss reduction, reliability improvement, and air pollutants diminishment [29,30] and roles markedly in the modern power grids. Apart from the RESs' advantages, they are of high uncertainty factor since their output power fluctuates, and this is a result from the climate changes [31].…”

The impressive furtherance of communication technologies has exhorted industrial companies to link-up these developments with their own abilities with the target of efficiency enhancement through smart supervision and control. With this in mind, the blockchain platform is a prospective solution for merging communication technologies and industrial infrastructures, but there are several challenges. Such obstacles should be addressed to effectively adopt this technology. One of the most recent challenges relative to adopting blockchain technology is the energy consumption of miners. Thus, providing an accurate approach that addresses the underlying cause of the problem will carry weight in the future. This work addresses managing the energy consumption of miners by using the advantage of distributed generation resources (DGRs). Along the same vein, it appears that achieving the optimal solution requires executing the modified reconfirmation of DGRs and miners (indeed, mining pool systems) in the smart grid. In order to perform this task, this article utilizes the Intelligent Priority Selection (IPS) method since this method is up to snuff for corporative allocation. In order to find practical solutions for this problem, the uncertainty is also modeled as a credible index highly correlated with the load and generation. All in all, it can be said that the outcome of this research study can help researchers in the field of enhancement of social welfare by using the proposed technology.

“…The problem with unknown inputs is common in daily business applications, for example, electric vehicle driveline [2], lithium‐ion battery current estimation [3], power system state estimation [4, 5], fault detection [6], and many others. For linear discrete systems with unknown inputs, an unbiased minimum variance (UMV) estimation algorithm is proposed based on the Kalman filter [7, 8]. This two‐stage state estimation algorithm estimates the state variables and unknown inputs at the same time.…”

This paper proposes a state estimation approach ‘robust strong tracking unscented Kalman filter with unknown inputs’ that can be applied to non‐linear systems with unknown inputs. Specifically, the non‐linear state and measurement equations are linearised by statistical linearisation. Then, the estimation equation of the unknown input is derived based on the weighted least squares method. The multiple suboptimal fading factor is introduced into a priori error covariance matrix to improve the tracking ability for the inaccuracy of the system model and the abrupt change of state variables caused by unknown inputs. Finally, based on the unbiased minimum variance estimation, the unbiased state estimation and the error covariance matrix are derived. Singular value decomposition is performed on the error covariance matrix to improve the stability of the algorithm. Simulated results validate the effectiveness of the proposed method.
