Abstract
Renewable energy sources (RESs), as clean, abundant, and inexhaustible source of energy, have developed quickly in recent years and played more and more important roles around the world. However, RESs also have some disadvantages, such as the weakness of stability, and by the the estimated increase of utilizing RESs in the near future, researchers began to give more attention to these issues. This paper presents a novel output power fluctuate compensation scheme in the small-scale power system, verifying the effect of output power control using storage battery, demand-response and RESs. Four scenarios are considered in the proposed approach: real-time pricing demand-response employment, RESs output control use and both of demand-response and RESs output control implementation. The performance of the proposed control technique is investigated using the real 10-bus power system model of Okinawa island, Japan. Moreover, the system stability is checked using the pole-zero maps for all of the control loops associated with the proposed scheme. The robustness and effectiveness of the proposed method was verified by simulation using Matlab ® /Simulink ® .

Summary
Even though diesel generators are still the most widely used resource around the world, they have several drawbacks: burning fossil fuel releases harmful emissions into the atmosphere and depletes the. Earth’s limited stored resources; this does affect the environment and increases the cost of generating dramatically because of the need to purify harmful emissions and the transportation adds extra cost [1]. RESs have many advantages: first, it is a clean source of energy, it means that it has low or zero carbon and greenhouse emission. It is renewable, and it implies that they do not deplete over a lifetime and there is zeroes possibility that they will run out. RES has many main forms such as solar power generation, wind generation, hydroelectric energy generation, biomass, hydrogen, fuel cell generation, and geothermal generation [2]
