The heating method is known as Direct Electric Heating (DEH) as the steel-built pipeline is heated by forcing single-phase current directly through the pipe steel. Qualified by Statoil in the mid-90s, there have been number of projects in the North Sea with more than 100 kilometres of pipelines heated by DEH. Another pipeline heating technology

2.1. Pumped hydro storage (PHS) PHS is a large scale energy storage system. Its operating principle is based on managing the gravitational potential energy of water, by pumping it from a lower reservoir to an upper reservoir during periods of low power demand.
The ideal battery model (Fig. 1 a) ignores the SOC and the internal parameters of the battery and represents as an ideal voltage source this way, the energy storage is modeled as a source of infinite power V t = V oc is used in the studies that do not require the SOC and transients in the battery to be taken into account.

This chapter presents an introduction to the Energy Storage Systems (ESS) used in the present power system. Nowadays, renewable energy sources–based generating units are being integrated with the grid as they are green and clean sources of energy and also address environmental concerns.
In its simplest form, a Power Plant, known also as a Power Station, is an industrial facility used to generate electricity. To generate power, an electrical power plant needs to have an energy source. One source of energy is from the burning of fossil fuels, such as coal, oil and natural gas. Then we also have nuclear power, and finally
Working principle: In a hydro electric power plant, water is stored in the dam reservoir which has potential energy. This potential energy is converted into kinetic energy when water from the dam is allowed to flow through the pipes. This kinetic energy is converted into mechanical energy allowing the water flowing in pipe to drive the turbine
Salaries, wages, repairs and maintenance costs are Rs. 6, 00, 000 / year. The maximum demand is 80 MW and load factor is 40 %. A power station has two 60MW units each running for 1500 hours a year. The energy produced per year is 700 x 106 kW-hr. Calculate the plant load factor and plant use factor.

Coal is burned in a boiler to produce steam, which spins a turbine connected to a generator. The steam is then condensed in a condenser and recycled to the boiler to repeat the process. The main components are
2.4.2 Power conversion system (PCS) The PCS of the energy storage system is as important as the storage container as the medium between the energy storage battery module and the power grid [ 94 ]. It is an important equipment for accessing the power grid and managing charging and discharging, and the stability of PCS plays a vital role [ 95 ].
Generator Working Principle: An electric generator works by moving a conductor through a magnetic field, inducing an electromotive force (EMF) based on Faraday''s law of electromagnetic induction.
Deaerator working principle, Types and Process Control. Deaerators is commonly employed in any chemical process industry or in Power Plants wherever boiler is utilized for steam production from boiler feed water. Deaerator solves the aim of removal of unwanted dissolved gases and dissolved oxygen from the boiler feed water before going
Compared with the gravity storage power plant using a single giant weight, the modular-gravity energy storage (M-GES) power plant has better flexibility in
They can be classified into two main types: photovoltaic (PV) power plants and concentrated solar power (CSP) plants. Photovoltaic power plants convert sunlight directly into electricity using
In this paper, the AGC control strategy and the abnormal strategy of energy storage system are studied. Combined with the characteristics of regional power grid, the frequency regulation control strategy is optimized, and the AGC frequency regulation performance and depth of the target unit are significantly improved, which improves the
The total wind power is equal to the incoming kinetic energy of the wind stream. It can be expressed as: Total wind power, Pt = (ρACi3)/2. Where, ρ = density of air (in kg/m 3 ); A = rotor swept area = πr 2 (r = radius of blades in meters); C i = incoming wind velocity (in m/s). The density of air (ρ) is somewhat complicated since it
But the storage technologies most frequently coupled with solar power plants are electrochemical storage (batteries) with PV plants and thermal storage (fluids) with CSP plants. Other types of storage, such as compressed air storage and flywheels, may have different characteristics, such as very fast discharge or very large capacity, that make
Working of the diesel power plant is not the same as some other electrical power plants like a nuclear power plant, coal power plant hydroelectric power plant, etc. The working of diesel power plant or basic working principle of diesel power plant is that thermal energy is converted into mechanical energy. This mechanical
Pumped-storage power plants are reversible hydroelectric facilities where water is pumped uphill into a reservoir. The force of the water flowing back down the hill is then harnessed to produce electricity in the same way as conventional hydroelectric plants. Their ability to store electricity makes them an effective tool to overcome the
