Energy interactions between in-home energy management (i-HEM) systems for enhancing resilience in smart residential microgrid

This paper presents an efficient model for optimal planning of electrical energy management in a smart residential microgrid (SRMG) by considering energy interactions among smart homes and with the purpose of SRMG’s resilience improvement. A two-state linearized mathematical programming framework is given for the development of such notions. The first state proclaims a regular, disruption-free SRMG state, whereas the second state declares a disturbed SRMG state. In the initial state, two steps are taken into account. In the first stage, the minimum energy cost for each smart home, and in the second stage, minimum load profile deviation for SRMG is considered. In the second state energy interactions among in-home energy management systems to enhance the resilience is deliberated. The main objective of these two states is to advance SRMG’s resiliency by considering modified SRMG’s load profile and minimized smart homes’ daily energy cost. Based on the obtained numerical results, energy interactions among smart homes have diminished smart home’s energy cost about 3.34% in normal state, modified SRMG’s load profile deviation about 3.62% in normal state, and improved SRMG’s resilience about 32% in disrupted state.
