An efficient technique‐based distributed energy management for hybrid MG system: A hybrid QOCSOS‐RF technique

Abstract

This paper proposes an efficient hybrid approach-based energy management strategy (EMS) for grid-connected microgrid (MG) system. The primary objective of the proposed technique is to reduce the operational electricity cost and enhanced power flow between the source side and load side subject to power flow constraints. The proposed control scheme is a consolidated execution of both the random forest (RF) and quasioppositional-chaotic symbiotic organisms search algorithm (QOCSOS), and it is named as QOCSOS-RF. Here, the QOCSOS can have the capacity to enhance the underlying irregular arrangements and joining to a superior point in the pursuit space. Likewise, the QOCSOS has prevalence in nonlinear frameworks due over the way that can insert and extrapolate the arbitrary information with high exactness. Here, the required load demand of the grid-connected MG system is continuously tracked by the RF technique.The QOCSOS optimized the perfect combination of the MG with the consideration of the predicted load demand. Furthermore, in order to reduce the influence of renewable energy forecasting errors, a two-strategy for energy management of the MG is employed. At that point, proposed model is executed in MATLAB/Simulink working platform, and the execution is assessed with the existing techniques.

IoT based energy management in smart energy system: A hybrid SO2SA technique

“…The subplot Figure 18A–F depicts the cost comparison of the proposed versus FA, proposed versus ALO, proposed versus RF‐FA, proposed versus QOCSOS‐RF, proposed versus OSA, and proposed versus SOA techniques, respectively. The efficiency of the recent strategy is gathered by comparing the outcomes with other approaches like FA, 52 ALO, 53 RF‐FA, 52 QOCSOS‐RF, 54 OSA, and SOA strategy. The battery is operated normally under the charging mode when the time interval t = 1–12 h. In these plots, operating costs and the overall cost of SO 2 SA technique are low rather than the other techniques.…”

“…Liu and Ding [27] studied distributed energy resources and concluded that customer satisfaction should be satisfied for the sustainability of these projects. Chen et al [28] aimed to generate an efficient distributed energy management system technique. They determined that the customers' expectations should be satisfied for the performance improvements.…”

A new energy management technique for microgrid system using muddy soil fish optimization algorithm

“…If the swarm size is continuously increased during the current iterative process, then every single fish updates its present location through Equation (35). Similarly, the current location of each fish is updated as per Equation (36), when swarm size decreases during the present iteration:…”

“…Chen et al 35 have proposed a hybrid two‐stage energy management technique for optimally managing the power flow across the distributed grid‐tied microgrid which includes renewable PV, wind energy system, fuel‐cell, and energy storage elements. The first stage is focused on optimizing the electricity cost using the quasi‐opposition‐based chaotic‐symbiotic organism search technique and power balancing is achieved in the subsequent stage by reducing the prediction errors for optimal demand prediction through the rain forest technique.…”
