Design a technically feasible solution to integrate an energy storage system into a grid-connected industrial site: Energy Management Assignment, RGU, UK

Coursework assignment

Design project

Design a technically feasible solution to integrate an energy storage system into a grid-connected industrial site, making use of power from renewable sources.

• Part A(40%): Build a model of the system (renewable generator, battery energy storage, and load) using HOMER Grid software and use this to evaluate optimal component sizing. HOMER mode! and initial report due Sunday 23 April (hand-in deadline 23:59}
•  Part B (60%): Investigate options for alternative energy storage systems. Final report due Sunday 14 May (hand-in deadline 23:59}

Coursework assignment

Part A

HOMER Grid model development due Sunday 23 April (hand-in deadline 23:59)
You have been given an Excel spreadsheet that shows:
° Grid electricity consumed at a healthcare facility in Northern Ireland in 2019 “grid import(1).csv”
* The time of use electricity tariff which applied for the year “Tariff G(1).json”
For the first part (Part A) of the assignment you are expected to:

1. Use the spreadsheet data to create a HOMER Grid model of the facility.

2. Add a 1 MW PV system to the model.

3. Use the HOMER Grid optimizer to suggest a suitable size of BESS for the facility.

4. Evaluate the sensitivity of HOMER’s BESS sizing suggestion by repeatedly running the model with slightly different input parameters to reflect uncertainties such as BESS costs, future costs of power from the grid, possible load variation, possible PV plant under-performance, etc.

5. Develop a range of scenarios to test resilience and reliability using the HOMER Grid outage function. Evaluate what effect these scenarios have upon the choice of BESS size.

Deliverables and marks:

• HOMER model (send me your *.hgrid file) — 10% of overall module mark
• Short report (max 3 pages) summarising key input values that you varied and what your findings are — 20% of the overall module mark
• Skeleton draft of the main report for Part B of the assignment — 10% of overall module mark
