A microgrid is a trending small‐scale power system comprising of distributed power generation, power storage, and load. This article presents a brief overview of the microgrid and its operating
The results show that the proposed microgrid system has 20.2 % lower total operating costs, 4.5 % lower carbon emissions, and 32.6 % longer battery life than the conventional microgrid system, which is critical for improving the operation stability, economy, low carbon of the system, and extending the service life of the battery.
In commercial/industrial and utility microgrids, soft costs (43% and 24%, respectively) represent significant portion of the total costs per megawatt. Finally, energy storage contributes significantly to the total cost of commercial and community microgrids, which have percentages of 25% and 15%, respectively, of the total costs per megawatt.
The U.S. Department of Energy commissioned the National Renewable Energy Laboratory to complete a microgrid cost study and develop a microgrid cost model. The goal is to elucidate the variables that have the highest impact on costs as well as potential areas for cost reduction. This study consists of two phases.
The analysis of total microgrid costs per megawatt shows that the community microgrid market has the lowest mean, at $2.1 million/MW of DERs installed; followed by the utility and campus markets, which have mean costs of $2.6 million/MW and $3.3 million/MW, respectively. Finally, the commercial market has the highest average cost, at $4 million/MW.
In a standalone microgrid system, prolonging the life of the equipment is necessary to reduce the cost of its replacement. However, the size and installation costs of the storage systems must be appropriate. Therefore, this paper provides an appropriate weighting to minimize the cost of the microgrid system.
The analysis shows that controller cost data as a percentage of total microgrid costs are relatively similar among the projects in our database and the NY Prize data despite the wide variety of system sizes, types, and uses. Controller costs per megawatt range from $3,500/MW to nearly $600,000/MW, excluding outliers, with a mean of $85,000/MW.
S&C Electric's categorization based on microgrid complexity2 The classification by microgrid complexity shows that costs for Level 1 projects have the lowest mean, at $2 million/MW (Table 2).
