Collaborative Buildings-to-Cloud Communication and Comparison of Service Broker Policies in Smart Grid

To fulfill the fluctuating demands of energy, there is dire need of energy management alongside the production of electrical energy. A number of management tools such as home energy management, demand side management and demand response are in practice in many electric power systems. Energy consumption is a real time activity therefore there is need of real time decisions. For real time decisions, the big data generated from energy management tools need to be processed in real time. Big data cannot be handled through traditional systems therefore there is dire need of efficient, reliable, scalable and cost effective system. Cloud computing provides the said required resources on demand. In this paper we simulated the use of cloud computing environment in smart grid. Two service broker policies are compared in term of processing time, response time, requests per hour and cost. To control congestion on network, a collaborative model for home to building communication is also proposed.
