BBO-based small autonomous hybrid power system optimization incorporating wind speed and solar radiation forecasting

—Hybrid power system consists of different sources of electrical energy with different operating times during different seasons. Deployment of a hybrid power system is expected in rural areas. Supplying remote load systems such as rural telephony, hospitals, military etc.., where continuous power supply is required, can be realized with the combination of wind and solar power. The proposed topology is designed for telecom load which uses dual input dc-dc fused converter for combining solar and wind energy sources. For the further research and improvements in the proposed fused converter topology, it is necessary to know in detail the power flow from solar and wind sources to the load or to storage battery depending on different seasons. For various wind speed with constant solar irirradiation and, for various solar irirradiations with constant wind speed, the power flow of the hybrid power system is simulated and presented. The same topology is investigated for different switching frequencies (10 kHz and 20 kHz), using MATLAB/SIMULINK, and the efficiencies are calculated.

Pumping Unit

Because the load of the oil beam pumping unit driven by pure electric motor changes sharply during operation, the power of the driving motor does not match and the energy efficiency is low. In this paper, a new type of wind-driven hydro-motor hybrid power system is proposed. The motor and the hydraulic motor are jointly driven, and the energy is recovered by a hydraulic pump with controllable displacement, so that the speed of the driving motor is relatively stable. In order to control the fan speed and keep up with the drastic changes of the outside wind speed, a control strategy of hybrid power system based on wind speed feed-forward compensation is proposed. Through simulation and experimental results, the following conclusions can be drawn: to begin with, the mathematic model is proved to be effective; next, simulation studies show that the proposed feed-forward control method can improve the response rate as well as reduce the response lag. This research can be a reference for the application of the feed-forward control method on the hybrid power system of beam pumping unit.system.

Real Scenario

One of the common problems faced by Telecommunication (TLC) companies is the lack of power supply, usually for those appliances with scarce chances of grid connection often placed in remote zones. This issue is more and more critical if the radio network has the specific task of guaranteeing the so-called “mission-critical communications”. This manuscript aims to propose and assess a viable solution to optimize the power supply and maintenance operations required to assure the proper functionality in such critical and remote sites. In particular, the main goals are defining a method to select the critical sites in an extensive and composite radio system and designing the hybrid power system in a way to improve the service availability and technical-economic benefits of the whole mission-critical TLC system. Finally, the proposed method and related procedures are tested and validated in a real scenario.
