We share many of the same energy challenges on our path toward achieving carbon-neutrality in our respective countries. For that purpose, the devices specified in the connection contract shall be installed in the wind farm; 4 the technical specifications and projects of the electrical part of the wind turbine or wind farm to be connected to the transmission network shall be approved by the transmission network operator before the commencement of the work. Power and energy reserves 1 The contingency reserve is intended for the replacement of unexpected outage of the production capacity or the transmission capacity.

In this case, the generator must switch over to auxiliary load. The generator shall be disconnected with as long a time-delay as the equipment enables. The generator must be able to operate on auxiliary load for at least one hour.
News & Events
The requirement concerning operating on auxiliary load is not applicable to wind turbines, wind farms and asynchronous generators. The system operator shall evaluate the reduction. The operation time within the frequency range of In exceptional cases the time for the elimination may extend to 0.
If faults occur in kV and 11kV networks, they shall be eliminated in 0. Such faults must not cause damages to power plant equipment. A generator and its auxiliary devices must withstand voltage variations, which do not prevent safe switching over to auxiliary load after disconnection from the network.
This requirement is not applicable to wind turbines and wind farms. Requirements applied to the power control devices 1 The power plant must have speed controllers of turbines and the relevant control systems. In this case, the generator supplies only the auxiliary devices of the power plant and the plant must operate at least for one hour.
The requirement specified in this subsection is not applicable to wind turbines, wind farms and asynchronous generators. Disconnected power plants enable to control the power in accordance with the orders of the system operator in order to restore the power system unity by resynchronisation.
Verification of conformity of generating installations to the requirements 1 The producer shall verify regularly the conformity of the generating installations of the power plant to the requirements established by this Regulation, starting from the commissioning to the end of their utilisation period.
The producer shall determine the frequency of verifications proceeding from the technical state of the system and notify the system operator thereof.
The measurement results of tests concerning the generating installation shall be capable of assuring proven traceability. The tests concerning the network shall be agreed with the system operator.
The requirements for control shall be laid down in the connection contract concluded between the network operator and the producer. A wind turbine or a group of wind turbines can be switched off in order to achieve quick curtailment of active power output. The reactive power supplied to or consumed from the network must be minimal. Automatic control of reactive power may be necessary if switching on and off of the connected wind turbine or wind farm or the lines connecting the wind farm to the network causes inadmissible voltage fluctuations for the consumers; 3 reactive power output shall be controlled by voltage on the upper-voltage or low-voltage side of the wind turbine. In the latter case current compensation shall be used; 4 the reactive power output shall be controlled by one central signal; 5 control set points and algorithms shall be changed by remote control.
Upon agreement with the system operator the tests may be partially substituted by imitation on a calculation model. The tests shall last up to 12 months, unless agreed otherwise by the producer and system operator.
The period may be extended, if testing could not be carried out for reasons beyond the control of the parties to the agreement.
This requirement is not applicable to wind turbines, wind farms and asynchronous generators; 3 to determine how the network operates at auxiliary consumption during one hour; 4 to check the conformity of the controllability of the generating installation to the control characteristics. Power control characteristics 1 Upon determining the start-up time of the generating installations of power plants participating in load control, it shall be taken into account that the start-up time from outage to full-load operation should be as short as possible.

The start-up times from the outage of equipment are the following: 1 in case of generating installation of thermal power plants from the cold state - up to 12 hours; 2 in case of gas-turbine units — up to 10 minutes; 3 in case of wind turbines and wind farms — up to 15 minutes in case of wind conditions which enable starting. The output power must comply with the requirements of § 27 of this Regulation; 2 if a power plant is used for frequency control, it shall be specified in a separate contract.
Primary and secondary control of active power of generating installation 1 If a power plant is used for primary and secondary control of active power, the system operator shall conclude a corresponding contract with the producer.
Subsections 2 — 9 of this section shall serve as a basis for establishing the technical conditions in the contract. The dead band of the speed controllers of the turbines shall be adjustable between ± 0— mHz with the deviation of ± 10 mHz.
It must be possible to switch primary control on and off both from the transmission network and in the power plant. The coupling of the common Nordic-Baltic electricity market to local district heating via power-to-heat, offers large comparative advantages with respect to flexibility of source, potential synergies, and economic considerations. It also facilitates the deployment of renewable energy, decarbonization of the electricity and heat sectors, as well as ensures a cost-effective energy supply.
This report illustrates the considerable potential and benefits of using heat pumps and electric boilers, which are promising options for curbing climate-warming emissions and developing the heating- and cooling markets in the Baltic countries. I hope that this report sheds light on the possibilities associated with heat pumps and highlights their significance for the green transition in the Nordic-Baltic region.
With growing interest, research must advance to reach our ambitious climate and energy goals by During the last couple of years, Baltic researchers have been involved in several other projects that Nordic Energy Research has initiated and funded, among which are the comprehensive reports Baltic Energy Technology Scenarios and Transport Statistical Data and Projections in The Baltic States
