Energy Generation Planning

Managing a power resource is a complicated task. Markets, prices and demand are constantly changing. And so are the resources - particularly in hydropower cascades. You need to know what resources you have, and what you will have in the near and distant future. Finally, the resources must be distributed and utilised throughout the cascade.

The hydropower cascade can be a complex system. Reservoirs, plants, rivers and tunnels are all a part of the planning process. To be able to optimise production, and to get the best payoff, you must take all the details into account. This is an impossible task if you don´t have the right tools.

Energy generation planning - Process based solution

Powel Smart Energy provides a complete solution for planning and optimising your hydropower cascade. The solution is defined in five main categories, as illustratied in the picture aboveexplained below. Within each category is a range of tools, task steps and functions such as input data control, simulation, optimization, scheduling, and analysis and trading tools.

The interface for the work processes setup is highly highly flexible in its configuration. Skilled and experienced Powel consultants help you to tailor processes and interfaces to your needs and requirements. The interface enables you to keep control of all your input data and results throughout the planning process. The procedure can contain numerous steps, and results from one step can provide input for the next.

While handling large amounts of data, it is important to stay focused. Powel Smart Energy gives you the opportunity to focus on the value-adding activities. The system takes care of the data, and guides you through the process. It makes sure the most relevant results are presented along the way and in the end.

Building a model

A model of the physical system is the foundation for planning and optimisation. All the physical elements of the hydropower system are described in detail, and connected together.

You use the model to simulate how the water travels through the cascade as power production is carried out.

Time dependent input data is fed into the model in the form of time series. These are connected permanently into the model. Input data can include:

If you enter a market price into the model, it returns an optimal production scenario as a result. This is the actual optimisation. You can also enter and simulate external factors such as restrictions due to fishing lisences, irrigation and bilateral agreements.

Important solutions

Energy generation planning ranges from long term seasonal planning to short term daily planning, and even intraday replanning. In intraday replanning it is particularly crucial to have efficient and safe work processes. Situations can be severe, and you must solve problems immediately. The seamless work processes in Powel Smart Energy are very suitable for these kinds of operations.

Finally, you can use the planning and optimisation results when bidding in the energy
