The power grid will change in the future when customers’ energy consumption habits change, more renewable energy sources are integrated into the grid and more Smart Grid functions are used. This will create some new challenges to the energy system, therefore, the power grid and supporting systems need to be able to react in different velocities to guarantee high-quality and reliable electricity distribution. The focus of this thesis is to find out which issues are creating different challenges to the energy system in in the timeframe of 4 hours of less, and to sort out alternative solu-tions to these challenges with evaluating their cost effectiveness. Market regulations are not covered in this thesis since they will be modified in the fu-ture. The main focus will be on Toshiba’s SCiBTM power energy storage. How it can be used to solve the new challenges and what would be the break-even point to make it a competitive choice. Visio 2035 is a research made by universities in Finland. That is the background with our own opinions and interviewing members of energy companies to predict changes in the future power system. When it is known what are the biggest challenges in the future, it is possible to discuss how power storages can be used as solutions. After knowing the possible solutions, it is calculated how much value can each service of power storage provide. Time of use for each service can be get from pilot projects. With the pilot project information and calculations for singular services, it is possible to know yearly income, operative costs and investment costs. Using these values, it was calculated that power storages are profitable investments already at present. It is also calculated break-even points for investments if the payback time needs to be shorter. |
