An Intelligent Energy Management System with an Interactive Local Power Market for a Grid-tied Community of Heterogenous Houses /

Abstract

Electrical energy management in modern communities is the need of hour particularly in smart grid paradigm. The proposed study is an efficient energy management system in a residential community of multi heterogenous houses. Real life grid connected community of heterogenous houses with some houses as prosumers and some as consumers, is modeled to form a transactive energy market. The houses are classified into three different categories based on inclusion or absence of PV, wind, and energy storage systems (ESS). As cumulative load of community is based on operating home appliances, the appliances in each house are managed by individual home energy management system (HEMS). HEMS schedule the appliances to meet the desired objectives of reduced operating cost, lower CO2 emissions, lesser grid dependency, increased life of batteries and maximal use of produced renewable energy. Different cases are simulated to test the effectiveness of the proposed system. The simulation results of various cases support the proposed study have cost reduction of 46.15 %, peak reduction 21.13 %, utility grid dependency reduction 31. 04 %, and reduction in emission of CO2 is 31.16 % (of 436 Kg/Day) to considered base case.
