Probability Analysis Improves Viability Potentials 

HOMER® Analysis Output

Various microgrid configurations yield not only varying degrees of predicted availabilities but also a wide distribution of  economic possibilities driven by large differences in equipment capital costs and levels of on-going support required.  These various configurations will also have different payback scenarios for each estimate of utility tariff change, fuel escalation assumptions, ancillary services prediction, etc.  Making an informed strategic choice on energy infrastructure upgrades require details on the range of options that provide the best opportunity for ecomomic viabilities. Financial analysis for this site was accomplished with three principal tasks: simulation, optimization, and sensitivity analysis:

Simulation

Models of microgrid performance for each particular system configuration each hour of the year to determine its technical feasibility, availability and life-cycle cost.

Optimization

For each of the various configurations prepared multiple optimizations under varying ranges of input assumptions are generated to gauge the effects of uncertainty or changes to modeled inputs. This process helped installation stakeholders understand the optimal value of each variable over which selection could be performed for design elements such as the mix of components that make up the system and the size or quantity of each.

Sensitivity Analysis

Sensitivity analysis was then performed to help site stakeholders assess the effects of uncertainty or changes in those variables which the team had limited control or ability to influence, e.g future fuel price.  Multiple optimizations were run prior to the sensitivity analysis to give a broader insight into impact of future tariff changes might have on microgrid viabilities.

Containerized Battery-in-Box (BiB) Solution Mitigates Corrosive Marine Environment

This maritime environment presented a unique set of operating and maintenance criteria, which included a high utilization factor combined with a depth-of-discharge that exceed 60%.  This demanding daily cycle profile coupled with the harsh marine location drove an atypical container with specialized environmental controls to preserve battery life and control equipment.
Li-ion battery storage would be housed in standard 40’ International Organization for Standardization (ISO) shipping containers. The containers are typically made from 12 to 14 gauge steel. Inverters and step-up transformers would be located within the container to protect conductors and electronics.  The Li-ion batteries (cells) would be arranged into modules, which in turn would be stored in battery racks. The container would have an access door at each end and overhead lighting on the interior roof. Each container would have an integrated heating, ventilation, and air conditioning (HVAC) unit located on the roof of the container.  An inverter with a battery management system and container control system would be installed externally on a concrete pad next to each container. A step-up transformer would be associated with a set of two containers and would be installed alongside the container on a separate concrete pad.  Integrated fire detection and suppression system for the nanophosphate chemistry would be installed if mandated by the local jurisdiction.
