Query: Fog Assisted Cloud Models for Smart Grid Architectures- Comparison Study
  and Optimal Deployment   Cloud Computing (CC) serves to be a key driver for fulfilling the store and
compute requirements of a modern Smart Grid (SG). However, since the
datacenters are deployed in concentrated and far remote areas, it fails to
guarantee the quality of experience (QoE) attributes for the SG services, viz.
latency, bandwidth, energy consumption, and network cost. Fog Computing (FC)
extends the processing capabilities into the edge of the network, offering
location-awareness, low latency, and latency-sensitive analytics for mission
critical requirements of SG. In this work, we first examine the current state
of cloud based SG architectures and highlight the motivation(s) for adopting FC
as technology enabler for sustainable and real-time SG analytics. Then we
present a hierarchical FC architecture for supporting integration of massive
number of IoT devices into future SG. Following this architecture we proposed a
cost optimization framework that jointly investigates data consumer
association, workload distribution, virtual machine placement and QoS
constraints towards viable deployment of FC model over SG networks. The
formulated MINLP problem is then solved using Modified Differential Evolution
(MDE) algorithm. Comprehensive evaluation of proposed framework on real world
parameters shows that for an infrastructure with nearly 50% applications
requesting real-time services, the overall service latency for fog computing
get reduced to almost half of that of generic cloud paradigm. It is also
observed that the fog assisted cloud framework lowers the aggregated
electricity consumption of the pure cloud computing paradigm by more than 40%.
