This article deals with load management system for a grid connected hybrid energy system coupled with battery for hospital load. In the proposed system, solar, wind, battery and grid are sources of energy proposed to supply hospital load. To enrich the energy efficiency of a proposed power system, Genetic algorithm (GA) is proposed in the scheduling operation. Transmitting ratio is the parameter optimised by GA to enrich the cost benefit and managing load demand. Time of Day pricing is a real time pricing system; it has turned out to be a successful strategy for lowering peak electricity demand across the board, but especially in developed nations. Using MATLAB, the proposed performance of GA in the aspect of daily cost benefit with the comparative analysis of conventional load management system. In this article analysis of LMS is validated with the experimental setup of 4 kW using Delta HMI and Embedded system with four sources and three loads. In this analysis Load management system is implemented using Delta HMI.
