Abstract

In the current situation, Renewable Energies are increasing significantly their installed capacity. However, in order to make the most of the installed capacity, a consistent planning and integration with the Grid must be ensured, as on the one hand the variable nature of Renewable Energies, especially Wind and Solar, makes more challenging the necessary balance between generation and consumption and, on the other hand, the prices must be sufficient to justify the great investments involved Perhaps the first idea that comes to mind when considering these circumstances is to store the energy when there is a generation surplus, so it can be poured back to the grid when the generation is not enough to cover the demand. This line of thought has led to some storage technologies being investigated, being the use of Battery Energy Storage Systems (BESS) one of the most considered ones, due to its flexibility and scalable nature. In order to ensure a continuous, safe and reliable operation of the grid at all times, not only must the generation be always well coordinated with the demand, but also the energy prices should be enough to sustain the investment efforts made. As not all the nodes in the grid are equally loaded and subjected to the same fluctuations in the demand or technical restrictions, as big consumers, and also big generators, have a specific geographic distribution in the Spanish Electricity Network. This Study is focused on addressing and demonstrating, using the Spanish Electricity Network as basis, that not only an optimum volume of storage can be calculated in order to maximize the penetration of Wind Energy into the Grid, but also that a consistent spatial planning is key to ensure the best use of such storage, minimizing technical restrictions while keeping the system economically viable.
