Abstract— In recent, Smart Grid is heading towards mega grid
with the integration of various consumer categories, renewable
energy penetration, bi-directional communication infrastructure,
and thousands of power buses interconnected in wide area
systems. With this growing trend, new terminologies evolve, such
as ‘Prosumers in energy district’ that refers to a special class of
consumers residing in the vicinity with the capability of producing
and consuming energy. Prosumers enhance the smart grid
infrastructure in terms of grid-support, bi-directional energy flow,
and stability enhancement. With Energy District (ED) as a
generating zone, the utility must undergo a Service Level
Agreement (SLA) that mutually satisfies the financial benefits.
Considering above, we propose a bi-directional energy
management model for an ED and Utility. Moreover, a Coalition
Manager (CM) is introduced that statistically correlates the
weather parameters with electrical load consumption of
consumers and controls the energy flows between both parties
under the principle of Service SLA. Furthermore, with climatic
drifts, an optimization model is developed that maximizes the
revenue of the utility. Under SLA umbrella, on Prosumers end, the
cost of energy consumption ($/MWh) is minimized and energy
surplus is maximized. To validate the aforementioned model, real-
time data of Texas State (US) is modeled and analyzed.

I. INTRODUCTION
A Smart Grid (SG) is the near-future power framework set
to achieve demand of electricity in a dependable, feasible, and
cost-effective way, employing advanced communication
technologies and advanced digital information. The focal
motive is to achieve energy sustainability, prevention of large-
scale failures, steady availability of power with reduction of
Capital Expenses (CAPEX) future for thermal transmission
networks and generators and optimized the Operational
Expenses (OPEX) of power distribution and production [1]. SG
is “the Future Grid” with an advanced, robust, and intelligent
system that maintains bi-direction Quality-of-Service (QoS)
between utility and consumers. In upcoming stations, end-users
must be active rather than desirable or static, and therefore the
power flow in SG is capable of dynamically switching between
consumers and local renewable energy suppliers [2].
In conventional power systems, drifts in demand and supply
will cause: (a) severe voltage dips, (b) imbalance circulating
currents, (c) problems of reactive and active power flow, (d)
tripping of the load breakers, and (e) degradation in the quality-
of-service. The power grid requires energy support to maintain
an optimum value of all electrical parameters at various buses
across the network. Failure to accomplish energy support will
result in massive blackouts affecting millions of consumers.
Moreover, with increased downtime will further affect the life
and reliability of the power system equipment drastically. With
advancement in an SG architecture, monitoring, and control,
EM of consumers and utility is enhanced. In [3], the authors
proposed a technique of Demand Side Management (DSM) that
estimate DSM in Electric Distribution System (EDS), based on
Time of Use (ToU) and elasticity pricing. The authors in [4]
presented a detailed study of the DR programs and DSM with
respect to power industry of China that included China energy
policy, Geographical Location (GL) of China, Economic status,
microgrid and SG in China, and power industry reform of
China. Furthermore, they developed electricity prices and status
of DSM in China providing a detailed analysis of DSM of
different countries.
One side of the research focuses on energy consumption and
demand management of residential consumers. The modeling
of DR program for consumers to optimizes energy usage was
explained in [9]- [12]. In [9], the authors described various
aspects of DR and SG that are recently employed, such as (a)
control protocols and communication for SG, (b) Architectural
models of DR, and (c) technology infrastructure for SG. The
authors comprehensively overviewed various DR techniques
and programs that motivated consumers to participate in DR
programs. Furthermore, different optimal controls are
employed for various optimization models for the DR schemes
[10]. The authors in [11] discussed in detail the four main
aspects of DR, such as (a) DR issues, (b) DR programs, (c) DR
