Electricity demand forecasting is an important procedure in the electricity market and plays a great role in assuring a sustainable and efficient operation chain. By accurately forecasting the demand, one can see a considerable reduction in production costs as well as saving energy resources. Therefore, optimizing the demand forecasting techniques became an inseparable goal of power economics, leading to the introduction of machine learning to this sector that proved to be superior to other pre-defined alternatives. This thesis proposes to apply a Hybrid model that combines two forecasting machine learning algorithms; namely Support Vector Regression (SVR) and Long Short-Term Memory (LSTM). The hourly data from the Spanish electricity market is used to forecast the day-ahead electricity consumption in the last quarter of the year 2018, with weather Variables being fed to the models as the inputs. The performance of the proposed model is compared with the Temperature regression and load projection model (the actual model used in Spain), Autoregressive Integrated Moving Average (ARIMA), Artificial Neural Networks (ANNs), and SVR and LSTM separately. The combined method's forecasting results were shown to be superior to all four suggested independent approaches, and it was able to successfully minimize errors and enhance the accuracy between actual and forecasted values. However, the proposed Hybrid model didn’t outperform the already applied approach and achieved a Mean Absolute Percentage Error (MAPE) of 1.71557 and a Mean Absolute Error (MAE) of 488.269.

Application of bagging in day-ahead electricity price forecasting and factor augmentation Özen, Kadir; Yıldırım Kasap, Dilem (2021-11-01) The electricity price forecasting (EPF) is a challenging task not only because of the uncommon characteristics of electricity but also because of the existence of many potential predictors with changing predictive abilities over time. In such an environment, how to account for all available factors and extract as much information as possible is the key to the production of accurate forecasts. To address this long-standing issue in a way that balances complexity and forecasting accuracy while facilitating th...
Hydro-Optimization-Based Medium-Term Price Forecasting Considering Demand and Supply Uncertainty İLSEVEN, Engin; Göl, Murat (2018-07-01) This paper proposes an electricity market model of Turkish electricity market for monthly and yearly electricity price forecasting in medium-term by means of supply and demand dynamics formed via a theoretical approach. The electricity market model created within this scope consists of three main components related to electricity demand, supply, and price segments along with hydro optimization submodel, which takes into account the nonlinear relation between supply and price. Electricity price is determined...
Data-driven modeling using deep neural networks for power systems demand and locational marginal price forecasting Jimu, Honest; Fahrioğlu, Murat; Electrical and Electronics Engineering (2022-9) Forecasting electricity demand and locational marginal prices (LMPs) have become critical components for power system security and management. Electricity Demand Forecasting (EDF) aids the utility in maximizing the use of power-generation plants and scheduling them for both reliability and cost-effectiveness. In this thesis, a novel Deep Neural Network Long Short-Term Memory (DNN-LSTM) forecasting model is suggested to improve accuracy and robustness for predicting hourly day ahead power system load and LMP...
A soft computing approach to projecting locational marginal price Nwulu, Nnamdi I.; Fahrioglu, Murat (2013-05-01) The increased deregulation of electricity markets in most nations of the world in recent years has made it imperative that electricity utilities design accurate and efficient mechanisms for determining locational marginal price (LMP) in power systems. This paper presents a comparison of two soft computing-based schemes: Artificial neural networks and support vector machines for the projection of LMP. Our system has useful power system parameters as inputs and the LMP as output. Experimental results obtained...
A novel methodology for medıum and long-term electricity market modeling İlseven, Engin; Göl, Murat; Department of Electrical and Electronics Engineering (2020-11-15) In the electricity market, there is a considerable degree of uncertainty in electricity demand, supply, and price due to the uncertainty in parameters such as economic growth, weather conditions, fuel prices, and timing of new investments, etc. These factors in return affect the predictability of the electricity market. This thesis aims to increase the predictability and observability of the electricity market by means of a suitable and validated electricity market modeling methodology designed for medium a...
