Generation of Hydro Energy by Using Data Mining Algorithm for Cascaded Hydropower Plant

Abstract

The thirst of the Earth for energy is lurching towards catastrophe in an era of increasing water shortage where most of the power plants are hydroelectric. The hydro-based power systems are facing challenges in determining day-ahead generation schedules of cascaded hydropower plants. The objective of the current study is to find a speedy and practical method for predicting and classifying the future schedules of hydropower plants in order to increase the overall efficiency of energy by utilizing the water of cascaded hydropower plants. This study is significant for water resource planners in the planning and management of reservoirs for generating energy. The proposed method consists of data mining techniques and approaches. The energy production relationship is first determined for upstream and downstream hydropower plants by using multiple linear regression. Then, a cluster analysis is used to find typical generation curves with the help of historical data. The decision tree algorithm C4.5, Iterative Dichotomiser 3-IV, improved C4.5 and Chi-Squared Automatic Interaction Detection are adopted to quickly predict generation schedules, and detailed comparison among different algorithms are made. The decision tree algorithms are solved using SIPINA software. Results show that the C4.5 algorithm is more feasible for rapidly generating the schedules of cascaded hydropower plants. This decision tree algorithm is helpful for the researchers to make fast decisions in order to enhance the energy production of cascaded hydropower plants. The major elements of this paper are challenges and solution of head sensitive hydropower plants, using the decision-making algorithms for producing the generation schedules, and comparing the generation from the proposed method with actual energy production.

An Effective Quantum Genetic Algorithm Based on Drama Resource Mining Using Wireless Sensing Technology

“…ough, the quality of the solution cannot be effectively improved by simply using Quantum Optimization Algorithm; therefore, there is a need to combine it with other techniques to further optimize the search capabilities of the algorithm. In [4,5], the authors stated that drama represents the integration of resources needed to develop drama and the implementation of localization and characteristic strategy of TV drama, while in [6], the authors explained how to effectively obtain drama resources in the network platform has become a significant problem to be solved. Many authors combined drama with today's technologies, that is, big data, wireless sensor technology, and artificial intelligence, to facilitate human from low cost, high speed, and low data consumption [28].…”

“…e development and maturity of TV drama is the combination of TV as a modern means of communication and drama as a cultural resource [2,3]. Drama represents the integration of resources needed to develop drama and the implementation of localization and characteristic strategy of TV drama [4,5]. How to effectively obtain drama resources in the network platform has become a significant problem to be solved [6].…”

Construction and Application of Reservoir Flood Control Operation Rules Using the Decision Tree Algorithm

“…The DT algorithm has the advantages of being easier to understand, being easier to implement, and requiring relatively less workload than other approaches. Therefore, it has been widely used to address water conservation problems such as flood forecasting [46,47], flood or drought risk assessment [48][49][50][51][52][53], flood or drought classification [54,55], water quality prediction [56,57], inter-basin water transfer dispatching [58], water level prediction [59,60], and hydropower station power generation dispatching [61]. Noymanee and Theeramunkong [46] adopted the boosted decision tree regression to forecast flood water levels in a real-time manner and achieved high forecasting accuracy.…”

“…Xi et al [58] used the decision tree method to determine the diversion amount according to the inter-basin water transfer rules. Parvez et al [61] proved that the C4.5 algorithm was more feasible for rapidly generating the schedules of cascaded hydropower plants. However, it has rarely been used in reservoir flood control operations.…”
