Cloud computing is a developing technology used for providing various services such as PaaS, IaaS and SaaS for various applications based on the pay as per usage. The foundation of trust is the assurance and confidence that information, people, entities, data, or processes will deliver the desired outcome with a particular level of assurance. Many times, users even do not have knowledge about processing their personal information over the clouds. In cloud computing, centralized architecture is used for trust modeling, which causes various trust and privacy issues. The trust model is subject to a number of limitations, including single point failure, overload, vulnerability to malicious assaults, particularly harmful recommendations, and lack of accessibility and untraceability of trust proof. There are numerous initiatives underway to increase confidence between cloud users and CSPs. The privacy issues including data leakage and compromising data integrity in the cloud environment. The blockchain technology can provide the solution for the above issues. The Blockchain technology has various advantages as it is decentralized in nature, immutable ledgers, providing full transparency, Instant traceability, data encrypted end-to-end. In the proposed system hybrid consensus algorithms are created to overcome problems of the existing blockchain consensus algorithm. By using blockchain technology creates a Blockchain as a Service (BaaS) in the cloud environment to improve the trust and privacy of users.

In the hierarchical control of an islanded microgrid, secondary control could be centralized or distributed. The former control strategy has several disadvantages, such as single point of failure at the level of the central controller as well as high investment of communication infrastructure. In this paper a three-layer architecture of distributed control is given, including the device layer, the control layer as well as the agent layer. The agent layer is a multi-agent system in which each agent is in charge of a distributed generation unit. Due to communication network constraints, agents are connected only to nearby neighbors. However, by using consensus algorithms the agents can discover the required global information and compute new references for the control layer. The proposed control system is tested on a microgrid scenario which includes paralleled inverter sources. For this, the system is implemented on a real-time cyber-physical test platform that combines real-time simulation models running in OPAL-RT with a network of ARM-based computers, representing the agents.

nowadays, developing electric vehicles (EVs) is an important measure to reduce the greenhouse effect of the traditional transportation system. While the number of EVs growing rapidly, how to charge EVs efficiently attracts researchers' attention. Different from the traditional centralized charging power allocation, which is operated by a centralized control computer collecting all information and sending the commands to EVs, in this paper the decentralized power allocation strategy for EV charging network is proposed. Moreover, the centralized algorithm requires a high quality communication network, which cannot handle disturbances in communication like delays or packet losses. Therefore, the consensus algorithm is applied here to realize the efficiency and robust power allocation of the EV charging network in a decentralized fashion. The effectiveness of the proposed strategy has been fully investigated in three different cases.
