Several industries have implemented grid connected solar PV power generation systems to fulfil their SPO and as a co-yield, they are meeting their partial power demands. Today smart grid systems are reliable and improve efficiency and security of electrical networks by making the grid controllable with continuous monitoring and automation. The smart grid system schedules and manages electrical demand in a reliable, economic, and sustainable manner. The smart grid system also possess demand response capacity to support and stabilize electrical consumption with electrical supply. The smart grid system has the potential to integrate new technologies to enable energy storage elements and the large-scale use of electrical installations, including transportation systems like electric vehicles. Proper control and management schemes are imperative to utilize the available electricity in an efficient manner and to avoid overdrawing power beyond the contractual demand. Through this paper, a novel smart grid scheme with intelligent load prioritization method is proposed for industries with grid integrated PV plants. A simulated smart grid scheme is proposed for implementation on an experimental basis in Tiruchirappalli unit of Bharat Heavy Electricals Limited (BHEL), one of the largest Indian engineering and manufacturing enterprises, catering to the needs of energy, industry and infrastructure sectors. This paper presents the design aspects, operational features and various control methodologies with simulation results. Such a smart grid scheme enables industries to have a greater control over their electricity consumption and also ensure compliance to demand-side regulations. The simulation results prove the proposed scheme is feasible and reliable for large scale integration in industries.
