“…3 The old Schoellkopf Power Station No-1, near Niagara Falls, began to generate electricity in 1881. 4 In 1886, the United States and Canada used 45 hydroelectric power stations to generate electricity, and that became 200 in the United States alone in1889. 5 In the Hydropower system, build a dam wall on a large river that has a large drop in altitude.…”

With the increasing population and standard of living, the energy demand is increasing. But the non-renewable resources are decreasing with the increasing demand for energy. So, we should focus on renewable energy resources. According to the report of REN21 in 2019, 73.8%of electricity is generated from non-renewable energy resources, and only 26.2%of electricity is generated from renewable energy resources where 15.8% is from Hydropower, 5.5% from Wind Power, 2.4% from solar PV (Photovoltaics), 2.2% from Bio-power and 0.4% from Geothermal, CSP and Ocean power. In this paper, we review the major renewable energy resources to determine effective and usable renewable resources. We especially focus on hydropower, wind power, and solar power, because those are the most used renewable resources at present. And finally, we develop a solar house system. To implement the solar house system, we used a solar array, a battery array, charge controller, inverter, and loads.

“…The lower branch reactance achieved by lowering the frequency improves the operation of both overhead lines [1] and cables [2] by easing limits related to transient stability, voltage stability, and thermal considerations. For more than a century, low frequencies, especially 16 2/3 and 25 Hz, have been used for transmission of railway traction power [4], [5] and for industrial purposes [6], applications which have benefited from the use of modern power electronics [7], [8]. Recently, offshore wind [9]- [11], and long distance overhead transmission [1], [12] have emerged as promising applications.…”

Advantages of operating portions of a power system at frequencies different from the standard 50 or 60 Hz have been demonstrated in the low frequency AC (LFAC) and high voltage DC (HVDC) literature. Branches constrained by stability or thermal limits can benefit from increased capacity and flexibility. Since advances in power electronics enable the choice of an operating frequency, tools are needed to make this choice. In order to quantify the advantages as functions of frequency, this paper provides models for steady state calculations with frequency as a variable and validates the modeling assumptions. It then introduces an analytical quantification of the power flow capacity of a transmission branch as a function of frequency, demonstrating different active constraints across the range of frequency. The modeling and power flow calculations are demonstrated for a practical transmission line using manufacturer data. The models presented here provide a foundation for system level studies with variable frequency using optimal power flow.
