An efficient reliability index for the assessment of energy efficiency considering sitting of green virtual resources in a microgrid

Energy efficiency program (EEP) is one of the demand-side management programs that can solve the demand-side and network-side problems. In this paper, a new concept of energy efficiency (EE) on the microgrid considering economic and technical impacts is introduced. The impacts of EE are considered on sitting of green virtual resources such as EEP as well as wind and solar power plants. The EE consists of two terms, economic and technical terms that are introduced in this paper. New indexes such as the efficient reliability index (ERI) are introduced to evaluate the EE. The presented model is implemented on the IEEE standard 33-bus test system. The model of the problem is the mixed integer non-linear programming (MINLP) and the problem is solved by the genetic algorithm in the MATLAB software. The results show the effectiveness of the proposed method and the presented model. •The impacts of green virtual resources are investigated to manage energy scheduling.•A mathematical model of the energy efficiency programs is suggested.•Techno-economic indices for energy efficiency evaluation are presented.•Optimal status of GVRs aiming at economic efficiency maximization is determined.
