The document discusses tidal energy and tidal power plants. Tidal power uses dams and turbines to harness the kinetic energy of tidal flows. There are different methods, including single basin arrangements that generate power on either the ebb or flood cycle, and double basin arrangements that provide continuous power with an upper and lower reservoir. While tidal power is renewable and pollution-free, development is limited by the need for suitable coastal locations, and construction and operation in the sea is challenging.

Non conventional energy sources
Ocean thermal energy conversion (OTECH) harnesses the temperature difference between warm surface waters and cold deep waters to run a heat engine and generate electricity. It works by using the warm upper ocean layer as a heat source to vaporize a working fluid like ammonia or propane, which then drives a turbine connected to a generator. The low pressure exhaust is then condensed back into a liquid using the cold water from the deep ocean and pumped back to repeat the process. While a promising renewable source of base load power, OTECH plants face challenges in efficiency due to pumping losses and high costs compared to other energy sources.
Tidal power 7
Tidal power harnesses the natural energy of tides to generate electricity using turbines. It consists of a turbine, generator, duct and removable cover anchored to the seafloor. Tidal power plants can be constructed by building dams or installing towers, with the largest dam-based plant in France. The best locations have strong, predictable tides and are in deep water away from coasts to avoid fishing and wildlife impacts. Tidal power has advantages of being clean, predictable energy without weather impacts, but disadvantages include limited resources, noise pollution effects on animals, and sediment damage risks to turbines.
Tidal energy
Tidal energy can be harnessed by constructing dams or barrages between tidal basins and the sea. During high tide, seawater fills the basin through sluice gates and turbines. During low tide, the water flows back to the sea through the turbines, turning them to generate electricity. There are different types of tidal power plants based on the number of basins and generation cycles. Single basin one-way plants generate power during ebb tides only, while double basin plants alternate generation between two basins to provide continuous power. Tidal energy is a renewable source but has high capital costs and generation varies with tidal patterns.

While tidal energy has advantages of being predictable, renewable and improving technologies are lowering costs, challenges include high initial costs and potential environmental impacts which require further study.
Tidal power
Tidal power harnesses the kinetic energy of tides to generate electricity and is a renewable source of energy. There are several methods of tidal power generation including tidal barrages, tidal lagoons, and tidal turbines. Tidal barrages involve constructing a dam across an estuary so that turbines can generate electricity from the ebb and flow of the tides. Tidal lagoons are similar but can be constructed anywhere with a high tidal range. Tidal turbines resemble wind turbines and generate power from tidal currents without blocking estuaries. While tidal power has advantages over fossil fuels, environmental concerns around impacts on ecosystems must still be addressed as the technology is developed further.
Tidal Power
Tidal power utilizes the kinetic and potential energy of tides to generate electricity through tidal barrages and tidal lagoons. Tidal barrages are dams built across estuaries to capture the energy of tides, while tidal lagoons enclose an area of sea with an embankment to harness tidal flows. The Severn Estuary in the UK has potential for a large tidal barrage with an estimated capacity of 8,640 MW. Tidal lagoons have lower environmental impacts than barrages and the proposed Swansea Bay tidal lagoon in Wales was found to be economically viable at a cost of 3.4p per kWh of electricity generated.

Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Non – conventional energy sources
- 2. NON – CONVENTIONAL ENERGY SOURCES TIDAL ENERGY
- 3. CONTENTS • Tidal Power. • Basic Principle of Tidal Power. • Characteristic of Tides. • Operation method. • Advantage and Disadvantage of Tidal Power.
- 4. Tidal power • Tide - periodic rise and fall - water tends - sea. • Tides occurs – action - sun and moon - water of the earth. • Dam - constructed across - mouth bay - separate basin and sea.(consist of large gates and hydraulic turbine) • Gates open – water fill in tidal basin. • Water is allowed – flow back – to sea – water turbine - dam
- 5. Contt.. Fig;1 principle of tidal power
- 6. Basic principle of Tidal Power • Gravitational attraction – moon(70%) and sun(30%) – water on the earth and ocean – produce tides. • In a Lunar days of 24hr 50 min two tidal cycles(2 high & 2 low). • Time between high & low is 6 hours. • High tides – at point directly under moon and diametrically opposite surface of earth.
- 7. Contt… • High tides occurs during full moon and no moon. Fig;2 Sea Tides
- 8. Contt… • Variation of tidal range durning a lunar months is as shown fig Fig3; variation in tidal range in a lunar month
- 9. Contt… • Tidal range – large – new moon – due to high gravitational force of sun and moon. • High tides – called SPRING Tide. • Low tides – called NEAP Tides. • Neap tides – during first & third quarters of the moon and sun and moon are right angle to the earth. • Tidal vary continuously during 29.5day lunar month.
- 10. Characteristics of TIDES • It is a periodical phenomenon, but in any tidal cycle, no two tides are alike. • Influenced by the relative position of sun and moon and their distance from earth. • The tides at full moon and no moon are higher than the rest. • The tidal range is not constant and varies continuously. • Mean tidal range vary from place to place. • Tidal range small at first quarter and third quarter moon
- 11. Operation methods of utilization of TIDAL energy • Tidal power plant are broadly classified into –Single basin arrangement »Single ebb cycle system »Single tide cycle system »Double cycle system –Double basin arrangement
- 12. Contt.. • Single basin arrangement – Single ebb- cycle system • During high tide – sluice gate – open and basin or reservoir is allowed to get filled.( turbine shut off) • Water level – basin rise till maximum tide level reached. • Sluice gate are closed as soon as the ebb tide is start (flowing back). • During ebb water flow from higher tide to lower tide sea level by passing through turbine by generating the power.
- 13. Contt… Fig;4 single ebb cycle
- 14. Contt… –Single tide cycle system • Power generated during flood tide. • Sea water flow into the basin after passing through the turbine, their by generating the power. • After food tide , sea level falls again and thus stops the power generation • Basin is drained by allowing to flow into the sea through the sluice ways
- 15. Contt… –Double cycle system • Power generation takes place using both ebb and flood tides • Uses reversible turbines • Turbine operates in both direction of water flow. • Power generate in both empty and filling cycles.
- 16. Contt…
- 17. Contt… • Double basin arrangement – This arrangement provides continuous power supply – Two adjacent basin – upper basin, lower basin – Dams are provide between each basin and sea and also between two basins. – Power house provided in dam. – Upper basin is filled by flood tide and lower reservoir empties at lower. – Head between the low and higher basin always help to continues production of electricity.
- 18. Contt… Fig 5; Double basin arrangement
- 19. Advantages of Tidal power plant • It is inexhaustible, independent of rain and its uncertainty. • It is free from pollution as it does not use any fuel. • As the plants are locate on the bays ,these do not require large area of valuable land. • It has unique capacity to meet the peak load demand, when it works in conjunction with thermal or hydroelectric plant
- 20. Dis-advantage of tidal power plant • Developed only if natural sites are available • Out from this not uniform. • Power station is in sea water materials may corroded. • It may effect fishing and navigation. • Construction of plant in sea is very difficult.
