Thermal Power Plants

It is well known that the electrical-power generation is the key factor for advances in any other industries, agriculture and level of living. In general, electrical energy can be generated by: 1) non-renewable-energy sources such as coal, natural gas, oil, and nuclear; and 2) renewable-energy sources such as hydro, wind, solar, biomass, geothermal and marine. However, the main sources for electrical-energy generation are: 1) thermal - primary coal and secondary natural gas; 2) “large” hydro and 3) nuclear. The rest of the energy sources might have visible impact just in some countries. Modern advanced thermal power plants have reached very high thermal efficiencies (55–62%). In spite of that they are still the largest emitters of carbon dioxide into atmosphere. Due to that, reliable non-fossil-fuel energy generation, such as nuclear power, becomes more and more attractive. However, current Nuclear Power Plants (NPPs) are way behind by thermal efficiency (30–42%) compared to that of advanced thermal power plants. Therefore, it is important to consider various ways to enhance thermal efficiency of NPPs. The paper presents comparison of thermodynamic cycles and layouts of modern NPPs and discusses ways to improve their thermal efficiencies.

Operating Constraints

The growing demand for electrical energy calls for the assimilation of renewable energy sources to the main utility grid. Multiple renewable energy sources (RESs) like solar PV array, wind turbine, micro-hydro plant, etc. can be combined and controlled to form a microgrid. In spite of the availability of different microgrid topologies, DC microgrid largely facilitates the injection of DC power from various renewable energy sources into the stabilised DC power pool. The requirement for a minimal number of conversion stages, simple structure, economic operation, and numerous localised applications are driving factors for the DC microgrid technology. The mettle of the DC microgrid technology lies in choosing the appropriate microgrid participants for energy interchange and the suitable supervisory control to tap power from the microgrid partakers even after respecting their operating constraints. The use of high gain DC-DC converters is inevitable in DC microgrid due to the low terminal voltage levels of different RESs.

The Cost

As the demand for electrical energy increases continuously, we cannot rely on the existing conventional source for continuous power supply, as they are diminishing fast. The renewable energy sources are the best alternative for this energy crisis. We have different types of renewable energy sources and choice of source depends on location and load requirement. The most prominent source is the solar energy because of its own advantages. The nature of supply from this source is DC and it is to be converted into AC for supply to consumers. However, inverters are used for this conversion but produces harmonics. The Multilevel inverters are the alternate choice over conventional inverters due to the advantages of Low dv/dt and lower switching losses. Out of various multilevel inverters, cascaded H bridge (CHB) MLI topology is a well known solution for reducing the harmonics, which needs more number of switches and isolation power supplies which further increases the cost. This paper describes a proposed hybrid H-bridge topology with reduced switches. The proposed topology is implemented in Matlab/Simulink and results for 5, 7, 9 and 11 level are analyzed with their THD in output voltage. Hardware model for 5-level inverter is developed using 8051 micro-controller and results are presented

Alternating Voltage

At the heart of a micro-grid that includes several sources of electrical energy, including renewable energy, there must be a base (reference) source that sets the voltage and frequency in the network. (Research purpose) The research purpose is in developing a basic voltage source of a micro-grid, which includes renewable energy sources. (Materials and methods) The article shows that the sources of electrical energy are different, but the main requirement for them is to be able to supply voltage to the electrical network at any time, there is a standard voltage scale in the network. For a micro-grid, which will include various sources of electrical energy with a total power of up to 25 kW, you can limit yourself to a voltage of 220 V and a single-phase electrical network. (Results and discussion) The article presents a block diagram; technical characteristics and electrical diagram of the inverter of a single-phase basic voltage source; a method for calculating the output filter of the inverter based on pulse-width modulation technology. (Conclusions) When using renewable energy sources in the micro-grid, it is necessary to take into account that there are periods of time in which they do not generate electrical energy and choose as the base one that will not have such moments, or you need to use a temporary electricity storage device. It is possible to use a chemical source or a battery of accumulators as a base source. When creating a micro-grid of alternating voltage, an inverter is added to these sources from constant voltage to alternating voltage. The article presents a block diagram of a base voltage source with an AC output reference voltage to create a micro grid with a power of up to 25 kW.
