Forecasting Electricity Prices: A New Approach

In today's world, electricity is an essential part of our lives. We rely on it to power our homes, keep our devices running, and ensure our daily routines go smoothly. With the rising demand for electricity, predicting its price has become increasingly important for both producers and consumers. Understanding how to forecast Electricity Prices can help businesses make better decisions, save money, and maximize profits.

#The Importance of Price Forecasting

Electricity prices can be quite unpredictable. They can change from hour to hour based on various factors such as demand, weather conditions, and energy sources used for generation. This unpredictability makes it challenging for companies to plan their operations and budget effectively. That's where price forecasting comes in. By accurately predicting electricity prices, market players can make informed decisions about when to buy and sell electricity, manage their resources more efficiently, and maximize their revenue.

#How Price Forecasting Works

Traditionally, there have been different methods for forecasting electricity prices. Some models focus on short-term predictions, which typically span hours or days, while others cater to medium or long-term forecasts, extending over months or even years. Short-term forecasting often relies on statistical methods, while long-term predictions tend to use techno-economic models.

Short-term models analyze various data points, such as electricity demand, fuel prices, and energy generation from renewable sources. However, they usually do this without considering the underlying economic principles that impact price formation. On the other hand, techno-economic models take a broader view of the market and consider factors like generation costs and supply-demand balance.

Both approaches have their strengths and weaknesses, leading to a growing interest in combining these methods to take advantage of the best aspects of each.

#The Research Gap

Despite many attempts to combine different forecasting methods, there has been limited research on whether information from techno-economic models adds any real value to short-term price forecasts. This raises the question of how effective these Hybrid Models can be, and whether they can significantly improve forecasting accuracy and financial outcomes.

#Our Objectives

In our study, we aim to bridge the gap between techno-economic energy models and advanced Machine Learning approaches using an ensemble deep-learning model. We want to find out if this combined approach can enhance the accuracy of electricity price forecasting. Our primary objectives are to:

1. Assess whether integrating information from a techno-economic model can improve the forecasting accuracy of machine learning models.
2. Evaluate the economic benefits that better price forecasts can bring, especially in terms of maximizing revenues from energy storage systems.

#The Methodology

To achieve our objectives, we first selected a reliable techno-economic model specifically designed for day-ahead price forecasts. This model simulates how electricity prices are formed by considering various factors such as supply, demand, and generation costs.

Next, we chose a machine learning model known for its accuracy-the Ensemble Deep Neural Network (Ens-DNN). This model utilizes deep learning techniques to capture complex patterns in the data, making it a strong candidate for price forecasting.

By combining these two models, we can create a more robust forecasting tool that leverages the strengths of both approaches.

#The Data

To conduct our research, we used historical data from the German day-ahead wholesale electricity market. This includes factors like electricity demand, fuel prices, generation from renewable sources, and more. By analyzing this data, we can build a better understanding of how various elements interact with one another and influence the price of electricity.

#Results and Findings

After applying our hybrid model, we found that integrating the techno-economic model with the Ens-DNN significantly improved forecasting accuracy. In fact, our model showed an improvement of about 18% compared to traditional methods found in existing literature.

This increase in accuracy translates into real economic benefits. For instance, when we tested our model against an energy storage optimization scenario, we discovered that improved price predictions could lead to a revenue increase of up to 10%. This result demonstrates the practical value of accurate price forecasts in the day-ahead market.

#Implications for Market Participants

The implications of our findings can be significant for various market participants, including power producers, energy traders, and utilities. Companies that can access more accurate price forecasts can make better decisions regarding when to buy and sell electricity, manage their production schedules, and optimize their storage operations.

By leveraging improved forecasts, these companies can gain a competitive edge, as they will be able to capitalize on market fluctuations more effectively than their competitors.

#The Future of Price Forecasting

As the demand for electricity continues to grow and become more complex, the need for accurate price forecasting will only increase. By combining advanced machine learning techniques with techno-economic models, we can create a more reliable forecasting framework that can adapt to the ever-changing energy landscape.

In the future, we expect to see more research exploring hybrid modeling approaches, incorporating new data sources, and refining existing methods to enhance forecasting accuracy further. The insights derived from such studies will continue to be crucial for various stakeholders in the energy sector.
