A Cost-Effective Multi-Verse Optimization Algorithm for Efficient Power Generation in a Microgrid

Abstract

Renewable energy sources (RESs) are a great source of power generation for microgrids with expeditious urbanization and increase in demand in the energy sector. One of the significant challenges in deploying RESs with microgrids is efficient energy management. Optimizing the power allocation among various available generation units to serve the load is the best way to achieve efficient energy management. This paper proposes a cost-effective multi-verse optimizer algorithm (CMVO) to solve this optimization problem. CMVO focuses on the optimal sharing of generated power in a microgrid between different available sources to reduce the generation cost. The proposed algorithm is analyzed for two different scale microgrids (IEEE 37-node test system and IEEE 141-node test system) using IEEE test feeder standards to assess its performance. The results show that CMVO outperforms multi-verse optimizer (MVO), particle swarm optimization (PSO), artificial hummingbird algorithm (AHA), and genetic algorithm (GA). The simulation results emphasize the cost reduction and execution time improvement in both IEEE test systems compared with other meta-heuristic algorithms.

A Droop-Controlled Interlink Converter for a Dual DC Bus Nanogrid with Decentralized Control

“…Then, the DAB in the dual DC buses nanogrid could be modeled with respect to the LV side in the dual DC nanogrid, as shown in Figure 9. For the study of the dynamic response of the DAB, the expression for the average value of the current injected in the LV DC bus should be linearized around an operating point, leading to a small signal model as in (6) [46]. However, the injected current ∼ i inj (s) as a function of the phase-shift ratio ∼ d(s) is needed to control the DAB based on the proposed V-I curve.…”

“…This is achieved with sophisticated information and communication technology (ICT) and modern power electronic converters [1][2][3][4]. The microgrids study has focused on distribution feeders and neighborhoods with medium-sized power plants, 100's kW [4][5][6]. The microgrids concept enables the distributed energy resources (DERs), which include power sources, energy storage units, and controllable loads, to operate in islanding mode following a power grid failure [2,5,7].…”
