Abstract
Energy systems have to deal with energy cost and environmental concerns such as greenhouse gas emission. Industrial buildings considered as Microgrid (μG) with heavy load worsen these issues even more. Further, cyber-attacks on the data communication channel between utility and customer is also a potential threat and may alter the data as well as the confidentiality of it, resulting in an inaccurate result. To address these problems, this paper proposes two-cored Building Energy Management System (BEMS) for Industrial Microgrid (IμG) with first cored termed as the energy layer concentrating on energy cost and emission reduction, while second cored termed as security layer provides the un-authorized intrusion detection and prevention system (IDS/IPS) for cyber secure communication of data. The μG under consideration contains national grid, Natural Gas (NG), solar Photovoltaic (PV) as input carriers; electrical energy at output ports; electric vehicle (EV) fleet; battery bank; solar PV panel as non-dispatchable Distributed Energy Resources (DERs) and Internal Combustion Engine (ICE), Fuel Cell (FC) and Micro Turbine (MT) as dispatchable DERs. Energy layer optimization problem has been solved in MATLAB using flower pollination algorithm for µG energy consumption cost and emission reduction. To develop and analyze the security layer, Linux operating system based Smooth-sec software has been used. Devised security layer continuously monitors the network traffic between customers and BEMS as well as BEMS and utility server. During monitoring it distinguish the licensed user or malicious attacker to detect and prevent possible internal and/or external intrusions in the communication channel. Results show that EMS reduces energy cost and emission in addition to cyber security from internal threats. Proposed two-cored control may be manufactured for utilities to realize its benefits for industrial customers in a smart energy distribution system.

Highlights
Rising fuel cost, imbalance in ecological system and overloading of energy resources need appropriate solutions
The results demonstrate that household comfort level increases from 40% to 100% by sacrificing 20% of energy cost
Keeping such efficient performance in view the proposed framework has been solved in Flower Pollination Algorithm (FPA)
Summary
Imbalance in ecological system and overloading of energy resources need appropriate solutions. Apart from research work on energy layer of BEMS a cyber security strategy needs to be developed to detect and prevent malicious attacks Such attacks may modify weather as well as tariff data and customer preferences causing BEMS to malfunction, resulting in erroneous energy cost and emission. EMS capable of optimally handling of bidirectional energy transaction with the national grid by scheduling the sources, load and storages for large scale industrial μGs, have not been proposed. EMS communicates with the building owner as well as utility via communication channels Such wireless or wired links remain under the threat of continuous unauthorized intrusion from external and/or internal intruders that may alter the parameters for instance weather and tariff data resulting in non-optimal schedule of μG components. The rest of the paper is organized as: section-2 presents the proposed two-cored energy management system for an IμG, section-3 presents first core i.e. energy layer, section-4 presents second core i.e. cyber security layer and section-5 draws the conclusion
