Efficient Utilization of Energy using Fog and Cloud based Environment in Smart Grid
Demand Side Management (DSM) is an effective and robust scheme for energy management, Peak to Average Ratio (PAR) reduction and cost minimization. Many DSM techniques have been proposed for industrial, residential and commercial areas in last years. Smart Grid (SG) gives the opportunity of two-way digital communication to consumers and utility. SG balances and monitors the consumption of electricity of the consumer. Moreover, it reduces the cost and energy consumption of the utility and consumer. There are several Smart Cities (SCs) in the world. These SCs contain numerous Smart Societies (SSs) which have the number of Smart Buildings (SBs) contain Smart Homes (SHs). When requests from the consumer side sent to acquire the resources other storage issues also increase. To make an environment more efficient and enhance the performance of SG, cloud is introduced. Reducing delay and latency in the cloud computing environment is a challenging task for the research community. The resources are required to process and store data in cloud. To overcome these challenges, another infrastructure fog computing environment is introduced, which plays an important role to enhance the efficiency of the cloud. The Virtual Machines (VMs) are installed at fog to whom consumers’ requests are allocated. In this thesis, the cloud and fog based integrated environment is proposed. The aim of this proposed environment is to overcome the delay and latency issues of cloud and to enhance the performance of fog. When there is a large number of incoming requests on fog and cloud, load balancing is another major issue. This issue is also been resolved in this thesis. The nature-inspired algorithms such as: Genetic Algorithm (GA), Crow Search Algorithm (CSA), Honey Bee (HB), Round Robin (RR), Particle Swarm Optimization (PSO) and Improved PSO by using Levy Walk (IPSOLW), Cuckoo Search (CS), CS with Levy distribution (CLW), BAT algorithm and Flower Pollination (FP) are proposed and implemented in this thesis. The aim of proposed GA and CSA is scheduling the load and minimizing the PAR and cost in SG environment. These algorithms also contribute in the cloud and fog based integrated environment of the thesis. To balance the load CSA, HB, IPSOLW, CLW, FP are proposed. The proposed algorithms are compared with implementing RR, PSO, and BAT. The comparative analysis of these proposed and implemented algorithms is done on the basis of service broker policies. The Closest Data Center (CDC), Optimize Response Time (ORT), Reconfigure Dynamically with load and proposed Advance Service Broker Policy (ASP) are also implemented in this thesis to evaluate the results of this thesis algorithm. On the basis of these policies, using aforementioned nature-inspired algorithms, the Response Time (RT), Processing Time (PT), VM cost, Data Transfer (DT) cost, Micro Grid (MG) cost and Total Cost (TC) is minimized in cloud and fog based integrated environment.
