Aiming at the problems of low energy efficiency and unstable operation in the optimal allocation of optical storage capacity in rural new energy microgrids, this paper proposes an optimization method based on two-layer multi-objective collaborative decision-making.
How does energy microgrid optimization improve voltage profile and network losses?
As can be observed, the voltage profile is improved and network losses have been decreased as a result of the energy microgrid's optimization through the selection of the best installation site and equipment capacity. The losses of the 33-bus network via the MOIKOA for Scenario#2.
Can storage-based Hybrid microgrids improve network performance?
Consequently, without considering the comprehensive forecasted data, the optimization and detailed planning of storage-based hybrid microgrids fail to inform the network planning of the logical capacities of storage to enhance the network's performance by better compensating for fluctuations in renewable energy sources' power.
The voltage deviation variations versus DOD%. In this study, a multi-objective structure for a PV/WT/BES microgrid optimization in a 33-bus network was implemented for minimizing the annual energy losses, to minimize the network bus voltage oscillations, and minimize the cost of purchasing power from the microgrid by the network.
Does microgrid multi-objective optimization increase energy costs?
The findings are cleared that microgrid multi-objective optimization in the distribution network considering forecasted data based on the MLP-ANN causes an increase of 3.50%, 2.33%, and 1.98%, respectively, in annual energy losses, voltage deviation, and the purchased power cost from the HMG compared to the real data-based optimization.
Can a PV/wt/BES microgrid optimize a 33-bus network?
In this study, a multi-objective structure for a PV/WT/BES microgrid optimization in a 33-bus network was implemented for minimizing the annual energy losses, to minimize the network bus voltage oscillations, and minimize the cost of purchasing power from the microgrid by the network. The problem is implemented in three scenarios.
As far as we are aware, using anticipated data for solving the microgrid optimization problem in the network is a more accurate method of optimizing the system for the day ahead of schedule than using actual or estimated data. Table 9 shows that, in scenario 2, the PV power has decreased from 470 to 234 kW.
