Electrical energy is one of the most essential forms of energy in modern society. It powers our homes, industries, transportation, communication and entertainment systems. It also plays a vital role in enhancing our quality of life, economic growth and environmental sustainability. However, electrical energy is not available in nature as such. It has to be generated from various sources, distributed over long distances and utilized for various purposes. These three aspects of electrical energy generation, distribution and utilization form the core of electrical engineering.

Economics of generation
The cost of electricity generation is one of the most important factors that determines the feasibility and profitability of a power plant. The cost depends on various factors such as capital cost, fuel cost, operation and maintenance cost, depreciation, interest, taxes and subsidies. The capital cost is the initial investment required to construct and commission the power plant. The fuel cost is the recurring expenditure on the fuel used to run the power plant. The operation and maintenance cost is the expenditure on the labor, materials and services required to keep the power plant running. The depreciation is the reduction in the value of the power plant over time due to wear and tear. The interest is the cost of borrowing money to finance the power plant. The taxes are the payments made to the government for using public resources such as land, water and air. The subsidies are the payments received from the government for promoting certain types of power plants such as renewable energy sources.
There are different types of power plants that use different sources of energy to generate electricity. Some of the common sources of energy are coal, natural gas, oil, nuclear, hydro, solar, wind, biomass and geothermal. Each source has its own advantages and disadvantages in terms of efficiency, reliability and environmental impact. Efficiency is the ratio of output power to input energy. Reliability is the ability to provide continuous and stable power supply. Environmental impact is the effect on the natural resources and ecosystems due to the power plant operation. Some of the common types of power plants are thermal power plants, gas turbine power plants, combined cycle power plants, nuclear power plants, hydroelectric power plants, solar power plants, wind power plants, biomass power plants and geothermal power plants.
The electricity generation can be optimized using various techniques such as load forecasting, load dispatching and load management. Load forecasting is the process of predicting the future demand for electricity based on historical data, weather conditions, seasonal variations and special events. Load dispatching is the process of allocating the available generation capacity among different power plants to meet the demand at minimum cost. Load management is the process of influencing the demand for electricity by offering incentives or penalties to consumers to shift or reduce their consumption during peak hours or periods of shortage.
The distribution system is the part of the electrical network that delivers electricity from the transmission system to the end users such as residential, commercial and industrial consumers. The distribution system consists of various components such as distribution substations, feeders, transformers, distribution lines, service lines and meters. The distribution substations are located near the load centers and step down the voltage from high to medium level using transformers. The feeders are medium voltage lines that carry electricity from the distribution substations to different areas or zones. The transformers are devices that step down or step up the voltage from one level to another depending on the requirement. The distribution lines are low voltage lines that carry electricity from the transformers to individual consumers or groups of consumers. The service lines are short lines that connect the distribution lines to the consumer premises. The meters are devices that measure and record the amount of electricity consumed by each consumer.
There are different types of distribution networks that differ in terms of voltage levels, configuration and protection. The voltage levels vary from country to country depending on their standards and practices. Some of the common voltage levels are 11 kV, 22 kV, 33 kV for medium voltage and 230 V, 400 V, 440 V for low voltage. The configuration refers to how the distribution lines are arranged or connected with each other. Some of the common configurations are radial, ring or looped and meshed or interconnected. The protection refers to how the distribution system is safeguarded from faults or abnormal conditions such as short circuits, overloads or lightning strikes. Some of the common protection devices are fuses, circuit breakers, relays and surge arresters.
The power losses and voltage regulation are two important parameters that affect the performance and efficiency of a distribution system. Power losses are the amount of energy wasted in a distribution system due to various factors such as resistance, leakage, corona and theft. Voltage regulation is the measure of how well a distribution system maintains a constant voltage at different load conditions. Power losses and voltage regulation can be minimized by using proper conductor size and material, optimal feeder length and location, optimal transformer size and location, optimal voltage level and regulation equipment such as tap changers and capacitors. 71b2f0854b
