Technical Evaluation of Utility-Interactive Photovoltaic Power Generation System with Energy Storage based on the Experimental Setup

There is harmful air-pollution which mainly caused by raw-coal firing for heating purpose in Ulaanbaatar, Mongolia. Although dominantly utilization of electricity-powered warmers is good solution for this issue as same as highly developed countries, local power system currently in use has already been in over-stress during sundown interval as most of residents actively use home electric appliances. Therefore, the authors intend to lessen the polluted-ingredients of urban area air by using latest technology development. The distributed-generation system with renewable source and battery storage can be the bright solution. Within this paper, an appropriate configuration of the utility-interactive photovoltaic (PV) power generation system with energy storage (ES) for locals, and its operation principle are discussed. Subsequently, an adapted operation algorithm which gives an economical advantage, and contributes for grid impact is applied. Then, the experimental setup to verify the feasibility of recommended structure and operation algorithm is implemented. Development of the PV power generation system with ES will lead to a reduction in peak power usage, and lessened amount of CO2 emissions is expected to be resulted.
