Campus and Community Micro Grids Integration of Building Integrated Photovoltaic Renewable Energy Sources - Case Study of Split 3 Area, Croatia - Part A

Micro grids interconnect loads and distributed energy resources as a single con-trollable entity. New installations of renewable energy sources in urban areas, such as building integrated photovoltaic, provide opportunities to increase ener-gy independence and diversify energy sources in the energy system. This paper explores the integration of renewable energy sources into two case study commu-nities in an urban agglomeration to provide optimal conditions to meet a share of the electrical loads. Energy planning case studies for decentralized generation of renewable energy are conducted in highways 2 renewable systems energy plan-ning software for hourly energy balances. The results indicate that building inte-grated photovoltaic and photovoltaic in the case study communities can cover about 17% of the recorded electrical demand of both areas. On a yearly basis, there will be a 0.025 GWh surplus of photovoltaic production with a maximum value of 1.25 MWh in one hour of operation unless grid storage is used. This amounts to a total investment cost of 13.36 million EUR. The results are useful for proposing future directions for the various case study communities targeting sustainable development.
