    3. 3. Project Integration Management Energy Storage System NEEDS Project Charter Project Title: Installation of Energy Storage at Wind-Farm on Jeju Island Project Start Date: June 1, 2013 Project Finish Date: December 31, 2013 Budget Information: Jeju Smart-Grid Institute allocates KRW 3500M for this project, and more funds from the government are no more available. The majority of costs will be internal labor. Vendors for battery systems will be taken domestically. Project Manager: Jay Jae Jung, (404) 862-6019, dreamfct@gmail.com Project Objectives: It is a crucial project for the smart grid system of Jeju Island to deliver high quality and more reliable wind power with the most efficient energy storage system. Main Project Success Criteria: A chosen energy storage system should satisfy the minimum storage capacity with a less expensive rate. Approach: Research on which ESS is suitable for the wind-farm site in Hangwon. Roles and Responsibilities: Nick/Sponsor/CEO, Susan/Team member/Chemist Sing-Off:
    4. 4. Project Integration Management Energy Storage System NEEDS Project Management Plan Section Headings Section Topics Overview Goal: To alleviate fluctuation rates of power, and then to increase the stability of the grid Objectives: To measure an appropriate battery capacity by a means of computer simulations Assumptions: The case of Hangwon wind-farm site on Jeju Island (9.8MW) Deliverables: The most efficient and suitable battery system Scope: Cost-benefit comparison of currently commercialized energy storage systems Project Organization Internal Organization: TF team at the Jeju Smart-Grid Institute External Organization: TF team at Ministry of Knowledge Economy Managerial Process Plan Top Management’s Priority: To install proper battery capacities by May, 2014 Project Controls: Monthly meeting with all stakeholders, weekly meeting with teams Tools: Gantt Chart Change Control: Business Planning Div. at the government Technical Process Plans Data mining to gain information, Computer simulation to prevent risks and pursue efficiency Supporting Process Plans Verification and validation plan; Documentation plan; Quality assurance plan; reviews and audits; Problem resolution plan; Subcontractor management plan; Process improvement plan

    21. 21. Project Risk Management Energy Storage System NEEDS Understanding the uncertainty associated with operating variable generation systems helps manage the level of risk associated with delivering services. Figure 1 shows a schematic of energy flow considered in the optimisation framework. The optimization problem is then to determine not only the charge/discharge profile of the energy storage device over a period of time, but also to determine the most appropriate energy mix at any given time for charging the energy storage device and supplying energy to the grid.
    22. 22. Project Risk Management Energy Storage System NEEDS Objective  Alleviate fluctuations of energy provided from the wind-farm in Jeju Island  Estimate the optimum capacity of lithium-ion batteries  Prove the feasibility of the Lithium-ion battery system through a simulation Simulation Method  Simulation is the imitation of the operation of a real-world process or system over time. The act of simulating something first requires that a model be developed; this model represents the key characteristics or behaviors/functions of the selected physical or abstract system or process.

    30. 30. Project Risk Management Energy Storage System NEEDS Outcome (Juju island’s case)  The total installed capacity of wind-farm x 20% = Battery capacity - Smoothing Energy fluctuations generated from wind-farms - Preparing for the transient energy drop (covering up 10MW/min)
    31. 31. Project Risk Management Energy Storage System NEEDS Simulation result  To prove the suggestion, we compare real generating data and simulation data. As a result, we can expect very stable generating capacity of wind-farms by installing 20% of battery capacities. Also, we expect cost efficiencies.

Conclusion Energy Storage System NEEDS Suggestion for the application of Lithium-ion batteries Section Scenario 1 Scenario 2 Scenario 3 Governmental Funds 0% 77% Funded from Private equity ESS costs (20% of generation capacity) 3,400M 3,400M 3,400M Net Profit (DCF) -5,889M +3,251M ? • 77% of costs for the installation of the Wind-Farm site was supported by the government from 1998 to 2003. • Today, many stakeholders doubt about whether financial execution for the Wind-Farm site was proper or not. • At the beginning, the site was designed to install 15 wind power units, but only 12 units are working now. • The issue is replacement costs for all units, durability life of which is 20 years. If so, who will be in charge? • Under the current economic situation of Korea, we can no longer expect funds from the government. • Consequently, except for funds from private equities, Raising electricity prices or Reducing ESS costs can be a solution.
