Modeling and Practice of Wind/PV/Pumped-Storage Hybrid System

Abstract

This paper built a hybrid power system, including wind power, PV power and hydro power generation. It is presented mathematical model for the optional design of hybrid power system. The object of the model are to minimize the initial investment cost, power supply reliability and power complementation. The constraint condition are included system working, installed capacity and load balance, So the capacity matching model is established. A stand-alone photovoltaic of pasturing area is calculated by using the model. The result shows that the optional design model have an important sense, which improved power supply reliability, complementary characteristics of hybrid power and reduce the total cost of the system.

Control Strategy of the Pumped Storage Unit to Deal with the Fluctuation of Wind and Photovoltaic Power in Microgrid

“…The effectiveness of this method was fully verified in different cases. In [20], Yi et al constructed a hybrid output system including wind power, photovoltaic power, and hydroelectric power. The purpose of this model was to minimize the initial investment cost and improved the reliability and power complementarity characteristics of the power supply.…”

“…The results showed that the scheduling model had obvious advantages under multiple criteria. Similarly, literature [18][19][20] failed to consider the influence of the limited capacity of pumped storage units on the flattening of power fluctuations and whether it will cause the waste of renewable energy. In [21], Mohsen et al proposed the control method maximum power point tracking (MPPT) to optimize the efficiency and performance of PV power generation.…”
