[PDF Version]Burkina Faso had just 62 MW of installed PV at the end of 2020. The World Bank has agreed to support Burkina Faso's Sustainable Renewables Risk Mitigation Initiative (SRMI) to improve access to electricity in rural areas with $168 million.
The funds will be used to implement the country's Large Scale Solar and Rural Electrification Project. They will also support the government in outlining an upcoming tender for 325 MW of solar coupled with 335 MWh of storage capacity. Burkina Faso had just 62 MW of installed PV at the end of 2020.
“This new scheme will enable Burkina Faso to mobilize more than $400 million in private investment in solar production and innovative battery storage systems,” added Alexis Madelain, project team leader at the World Bank.
“This new project is in line with our strategy for the Sahel, which aims to double the rate of access to electricity by 2025, especially in rural areas, and to create the conditions for more private financing in the energy sector,” explained Maimouna Mbow Fam, World Bank operations manager for Burkina Faso.
SVCs are fast-acting reactive power compensation devices that adjust the reactive power flow by switching in or out thyristor-controlled reactors and capacitor banks based on real-time system conditions. Functioning: SVCs consist of thyristors, which are semiconductor devices used to switch electrical power circuits.
In this paper, the sizing and allocation of a fixed capacitor as a reactive power compensation device for a distribution network is studied. One is where the capacitor is installed and the other is that what the size of the capacitor is.
Mathematical formulation The reactive power compensation has been analyzed mainly as an optimization problem restricted to a single objective, which would provide a single optimal solution with a priority approach based on the adequate selection of capacity and location of capacitor banks.
Reactive power is either generated or consumed in almost every component of the system. Reactive power compensation is defined as the management of reactive power to improve the performance of AC systems. Why reactive power compensation is required? 1. To maintain the voltage profile 2. To reduce the equipment loading 3. To reduce the losses 4.
Static reactive power compensators can maintain a pre-programmed stable voltage level.
Use of capacitive (shunt compensation) on various part of the power system improves power factor, Reduce power losses, improves voltage regulation and increased utilization of equipment. Reference: Electric power generation, Transmission and distribution by Leonard L.Grigsby. Power system supply or consumes both active and reactive power.
Having said the types of compensation, in this article we are going to discuss mainly about Shunt compensation using Capacitor bank. Since most loads are inductive in nature they consume lagging reactive power, so the compensation required is usually shunt capacitor bank. Shunt capacitors are employed at substation level for the following reasons:
This is because the distribution grid in half voltage has no other type of capacitive compensation because the distribution grids have short distances for the transport of energy, voltage levels below 34.5 kV and the largest component of conductors are bare wires.
Using a magnifying glass on a solar panel has a tantalizing promise—it can potentially boost the power output of your solar panel, translating to more energy savings and a reduced carbon footprint.
The super focusing properties of magnifying glass have lit the paper on fire. The idea is simple, can we use a magnifying glass to increase our solar production? Yes, we can. The concept of concentrating solar power is an understudy for over a decade now, and scientists are close to making a breakthrough product in the photovoltaic industry.
For one: Magnifying glasses increase heat intensity in a focused area, but the photovoltaic process that makes solar marvelous is based on light, not temperature. High heat is not friendly to most building materials, ultimately including solar panels, although they are designed to function well north of three digits Fahrenheit.
While this is an interesting concept and not categorically implausible, we don't know of anyone who has made such a notion practical yet.* For one: Magnifying glasses increase heat intensity in a focused area, but the photovoltaic process that makes solar marvelous is based on light, not temperature.
Concentrated solar power (CSP) systems utilize sunlight to generate electricity using reflecting equipment such as troughs or mirrors. As far as energy storage and efficiency are concerned, CSP is superior since it uses TES technology to store energy.
Integrity is a trade skill, too. As to the plausibility of magnifying glasses magnifying energy output: A few years ago IBM actually experimented with this idea to improve solar energy output. To achieve it, IBM incorporated a liquid metal thermal cooling system onto ordinary PV cells.
So we have only seen concentrating solar power in large thermal power plants. It works on a fundamental principle of focusing the direct sunlight to a receiver that intelligently passes it to some storage. The heat energy in the storage passes on to the thermodynamic cycle to produce electricity.
Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10, up to 10, cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 13.
The flywheel energy storage systems can be used for stability design in high power impulse load in independent power systems [187, 188]. A combined closed-loop based on the genetic algorithm with a forward-feed control system with fast response and steady accuracy is designed .
Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy.
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel's secondary functionality apart from energy storage.
Flywheels with the main attributes of high energy efficiency, and high power and energy density, compete with other storage technologies in electrical energy storage applications, as well as in transportation, military services, and space satellites .
A Flywheel Energy Storage System (FESS) is defined as a system that stores energy for a distinct period of time to be retrieved later. There is a class distinction between flywheels used for smoothing the intermittent output of an engine or load on a machine and these energy storage systems.
Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel's secondary functionality apart from energy storage. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
Lead-acid batteries have a lower energy density (30-50 Wh/kg) and specific energy (20-50 Wh/L) compared to lithium-ion batteries (150-200 Wh/kg and 250-670 Wh/L, respectively).
For comparing devices in practice, the values in Wh or W max are divided by the volume or weight of the storage unit. Lead acid batteries have an energy density of 30 Wh/kg. The figures above were taken from Wikipedia. The figure at the left describes the energy density per weight as a function of the energy density per volume.
The lead acid battery in the charged state has a positive electrode with a lead core, a shell of lead (IV) oxide (PbO 2 ), and a negative electrode of finely divided porous lead (lead sponge). The electrolyte is a dilute (27%) sulfuric acid (H 2 SO 4 ). In the discharged state, both poles are made of lead (II) sulfate (PbSO 4 ).
Batteries use 85% of the lead produced worldwide and recycled lead represents 60% of total lead production. Lead–acid batteries are easily broken so that lead-containing components may be separated from plastic containers and acid, all of which can be recovered.
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
Lead battery technology 2.1. Lead acid battery principles The nominal cell voltage is relatively high at 2.05V. The positive active material is highly porous lead dioxide and the negative active material is nely divided lead. The electrolyte is dilute fi aqueous sulphuric acid which takes part in the discharge process.
Lead–acid batteries have been used for energy storage in utility applications for many years but it has only been in recent years that the demand for battery energy storage has increased.
