DENMARK'S EXPERIENCE IN FORECASTING AND BALANCING WIND AND SOLAR ELECTRICITY

From 18 to 20 March 2019, the Ukrainian delegation composed of representatives from the Ministry of Energy and Coal Industry of Ukraine, SE NPC “Ukrenergo” and the Ukrainian Wind Energy Association studied the Denmark's experience in balancing the energy system, security of supply and demand management. A series of workshops and meetings were held in Denmark within the framework of bilateral intergovernmental cooperation under the Agreement on Development and Co-operation of the Ukraine-Denmark Energy Centre (UDEC) concluded by the Ministry of Foreign Affairs of the Kingdom of Denmark and the Ministry of Energy and Coal Industry of Ukraine.

The Ukrainian delegation headed by Olga Buslavets, Head of the Ukrainian-Danish Energy Centre, General Director of the Energy Markets Directorate of the Ministry of Energy and Coal Industry of Ukraine, visited the head office of the Danish system operator Energinet.DK. to learn of the work the dispatching centre, the functioning of electricity markets, primarily day-ahead, intra-day and balancing markets. Particular attention was paid to the forecasting and balancing of wind and solar electricity, as well as to the use of appropriate methods and technologies to ensure the security of supply.

Ukrainian experts also visited 400 kV station in Fraugde near Odense.

In a meeting with representatives from VESTAS Ukrainian delegation discussed the issues related to forecasting the electricity output from wind and solar power plants for both intra-day and day-ahead markets, as well as long-term forecasts. Ambassador of Ukraine to Denmark Mykhailo Vydoinyk attended the meeting. The Danish companies ENFOR and CONWX with international experience in the forecasting sector, presented their methods and tools for forecasting wind and solar electricity generation.

Commenting on the need to introduce RES auctions in Ukraine, Olga Buslavets emphasized that the Ministry of Energy and Coal Industry of Ukraine, as the central executive authority responsible for the Ukrainian Electricity Market development policy had to ensure an adequate electricity price for consumers and create favorable conditions for attracting investment in the renewable energy sector. “Certainly, our plans include further steps in synchronizing our energy system with the European ENTSO-E network and integrating the Ukrainian electricity market into the European one. This is our medium-term perspective and to meet all the conditions for future synchronisation we will have to prove our balancing sufficiency. This task is complicated by the fact that the active growth of RES in the absence of responsibility for imbalances does not give the right signals for investors to build balancing capacities and improve electricity generation forecasting. The Ministry has developed and is currently finalizing the tender procedure for the construction of generating capacities. This document sets out the rules and guarantees for an investor who is prepared for construction of generating capacities necessary for the Ukrainian energy system, in particular - highly maneuverable ones, which in turn will allow to integrate more RES into the energy system. I would not want investors to see increased responsibility for imbalances as additional costs. On the contrary, given the lack of regulatory capacities, investments in the highly maneuverable generation or in energy storage facilities are promising businesses in our country”.

It’s worth noting that the development of renewable energy in Denmark has been facilitated not only by the political will and the desire of the Danes to move from fossil fuels to green energy, but also by the existing technical capacities. For example, electricity generation from wind reached 115% on 19 March 2019; surplus electricity was exported to other European countries through the network of interconnectors.

According to Andriy Konechenkov, the Chairman of the UWEA Board, WWEA Vice President “integration of the United Energy Systems of Ukraine into the European ENTSO-E network, which is provided by the Association Agreement between Ukraine and the EU, will also solve the problem of overproduction of “green” electricity in Ukraine. Due to the high share of nuclear power generation, Ukraine requires highly maneuverable capacities and more accurate forecasting of solar and wind generation. And these problems need urgent solutions”.

The Ukrainian Wind Energy Association expresses its gratitude to the Ukraine-Denmark Energy Centre for the opportunity to participate in the events.
