Power mismatching between the generated and consumed power is caused by the stochastic and unpredictable demand energy, resulting in increasing the electricity bill and the load energy waste. A consensus algorithmbased coalition game theory for optimal demand management scheme is proposed for multi-agent smart microgrids (SMGs). The consensus algorithm depends on the information and data transfer among the neighbors in the multi-agents SMGs. The consensus algorithm for the demand management system has been proposed to improve the coalition game theory. The allocation of the surplus energy on the deficient customers is based on Shapley value, which enables the unequal distribution of power according to the demand. The computational and storage units are shifted to the Fog layer to deal with the multi-agents SMGs' extensive data and information. The proposed method's main objectives are minimizing the energy cost, energy waste in the presence of packet losses, and power mismatching. A hypothetical SMG system has been simulated and modeled using the MATLAB environment program to prove the proposed method's effectiveness. Three scenarios are performed, including without a demand management system, coalition game theory only, and consensus algorithm-based coalition game theory. A comparison between the obtained results has been performed. Sensitivity analysis based on the increasing of iterations and the number of homes is performed to prove the effectiveness of the proposed method. Also, a comparison between the optimization outcomes obtained results is implemented using genetic algorithm (GA), particle swarm optimization (PSO), ant colony optimization (ACO), and artificial bee colony (ABC) optimization techniques. The results prove the applicability and feasibility of the proposed method for the demand management system in SMG. The proposed method achieves an improvement of 8.056%, 6.629%, and 98.888% for the incremental cost, the total electricity bill, and load energ

Droop control is one of the basic control methods to solve the problem of load sharing in DC microgrids. However, the conventional droop control cannot balance the current sharing accuracy and bus voltage regulation between microsources(MSs). To tackle this problem, the ideal output current of each MS can be obtained based on the dynamic consensus algorithm. Then an improved droop control method that changes the droop coefficient by fuzzy control is proposed to improve the robustness of the system. The bus voltage can be effectively controlled while the currents are accurately shared. Finally, the effectiveness and superiority of the proposed droop control strategy are verified by MATLB/SIMULINK simulation.

The rapid development of blockchain technology has given rise to many applications like digital currency. Building a consortium blockchain for a bidding system is a promising way to benefit the bidding businesses, by reducing cost and sharing data among tenderers and bidders. Generally, Practical Byzantine Fault Tolerance (PBFT) algorithm is the wide-ly-used consensus algorithm in a consortium blockchain. However, this algorithm meets its bottleneck, when there are a large number of nodes in the consortium blockchain net-work. In order to enhance the scalability of the consensus algorithm, this paper puts for-ward an advanced PBFT-based consensus algorithm, named ANPBFT, by taking ad-vantages of the message aggregation technology and tree topology technology. Specially, the consensus nodes in our proposed algorithm are divided into active nodes and passive nodes. Then, the consensus of block information is equivalent to the confirmation of iden-tity aggregation signature and aggregation promise of information key. The experimental results show that our proposed algorithm has better performance than the original PBFT algorithm. It also shows good scalability and can be used in a large-scale license-chain system.

This article focuses on the application of blockchain consensus algorithms in the power energy trading system and the comparison of these algorithms such as PBFT(Practical Byzantine Fault Tolerance), Raft and IBFT(Istanbul Byzantine Fault Tolerance). The article introduces the concept of blockchain consensus algorithms and its application in power energy trading system. It then provides a brief overview of the three algorithms and their underlying structures. The comparison of the algorithms is done in terms of features such as scalability, reliability and security. The article also provides an overview of the advantages and disadvantages of each algorithm and its application in power energy trading system. We examine the blockchain partition algorithm improved by the integration of Raft consensus and IBFT consensus, with a special focus on the advantages of using a hybrid algorithm in distributed networks. We discuss the need for consensus algorithms that are well-suited to blockchain networks and the improved security provided by a consensus algorithm incorporating both Raft and *** also discuss the implications of incorporating Raft and IBFT into a blockchain partition algorithm and its potential scalability. In conclusion, we provide a synthesis of our research, with potentials for further studies and contributions in this field.

consensus is one of the most actively studied topics within the realm of multi-agent systems. It generally aims to drive flocks to achieve a common group objective. In this study, a Cucker-Smale model for consensus algorithm has been implemented to resolve the issue of flocking for power systems. By using this model, consensus can be achieved by randomly chosing the initial positions and velocities of the birds with a minimum number of iterations. Moreover, at the end the simulation results for 7 and 25 birds have been presented to confirm the convergence of the agent's average velocities and directions.

consensus algorithm is a key component of the blockchain technology, and also a hot topic in distributed system research. Under the background that blockchain technology has entered the development stage of consortium blockchain, the Practical Byzantine Fault Tolerance (PBFT), proposed by Miguel and Liskov in 1999, occupies an vital position. Although PBFT has many advantages, it does not scale well because of O(n(2)) communication complexity. In order to solve this drawback, we present a hierarchical and group-based BFT consensus algorithm - efficient BFT (EBFT). It utilizes a novel network topology to effectively reduce communication times among nodes and provides O(n) communication complexity. The experimental results show that EBFT optimizes the consensus process involving large-scale nodes, so that the consortium blockchain can be applied to a wider range of application scenarios.

The backbone of Blockchain technology is a consensus algorithm because it plays a significant role in terms of network efficiency, security and scalability. Currently, a consensus algorithm is the hot research topic since many of the existing consensus algorithms are facing some issues in terms of low throughput, high latency, high bandwidth consumption and CPU utilization. Therefore, to ensure high performances, this paper proposed a novel consensus algorithm based on nodes trust values for consortium blockchain. The proposed paper divides mining nodes of the network into two groups basis on trust values. A mining node is randomly nominated as a leader node from the group of high trust values. This improves network performances by increasing throughput, reducing latency, reducing communication overhead cost and CPU utilization. Hyperledger Fabric v2.1 is used to check the performances of the proposed consensus algorithm. The result shows that it has better performances in term low latency, high throughput, low communication bandwidth cost and low CPU unitization.

Blockchain technology has gained immense popularity over the last decade. It has transformed several industries by enabling processes to work in a secure and decentralized manner. Blockchain consists of blocks that are linked together through cryptography. Blockchain is a distributed ledger that contains a set of sequenced blocks of data. Each block records transaction data in a transparent, immutable, and secure fashion. consensus algorithm is the key part of this technology as it is used for the decision-making process among nodes in the blockchain network. Nodes in the verifying network use consensus algorithm to reach mutual agreement about state of the blockchain whenever a new block is added. This makes it possible to accept any transaction in the blockchain. Many consensus algorithms have been proposed in the literature each having its own performance and security characteristics. In this paper, we present a pattern for one of the most widely used blockchain consensus algorithms, which is the Proof of Work (PoW) algorithm. This paper is a part of our project on blockchain architecture and patterns.

In order to improve the authenticity and credibility of agricultural products traceability information, this paper proposes an improved blockchain consensus algorithm FPBFT for the whole process traceability system from planting to consumption of agricultural products supply chain based on blockchain, in view of the high communication overhead and low efficiency of the consensus algorithm PBFT of the coalition blockchain when the information is on the chain. The credit value of the nodes is calculated based on the behavior of each node in the consensus process, and the nodes are given different voice rights based on the credit value;then a simplified consistency protocol is proposed to reduce the time complexity by combining the node characteristics of the coalition chain. Finally, a comparison experiment is conducted to verify that the improved PBFT algorithm can reduce the communication volume and improve the efficiency.
