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.
