Feasibility and simulation study of high-rise building Micro-grid with PV and mini-hydro pumping

Electrical load is centralized in city, especial in high-rise building which not only has PV generation resource but also has a gravity potential. The height in range of 30–400 meters, are everywhere in city. Water is also a necessary resource that city should have; water storage in the roof, or water body in waist, and a water tank underground of a building or a building group, is not a very difficult to build them, in fact, water system including pumping system has already been implemented in those buildings for water drink, sanitation, swim pool, fire control, water drain, etc. The hydro pumping generation will only added some new space, weight-bearing, new mini hydro pumping system, etc. A micro-grid development scheme of PV and mini-hydro pumping is presented and the focus is on the daily and short-term operation simulation and parameters selection of such scheme.
