The system operator shall evaluate the drop. If the device has more than one superheater, a delay is accepted due to time constant caused by the additional superheater. The requirements for control shall be laid down in the connection contract concluded between the network operator and the producer. System operation control in an interconnected system 1 If a system operates in an interconnected system and if in accordance with the contract the operator of the interconnected system is assigned to organise the management of a part of the interconnected system, the contractual tasks concerning the organisation of the interconnected system will take precedence over the tasks concerning the organisation of the operation of the of system and the system operator shall execute the instructions of the operator of the interconnected system first. 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 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 Trading Wind System 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. For that purpose, the appropriate measuring devices shall be installed to the wind turbine or the wind farm in accordance with the connection contract.
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.
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. As a rule, the transmission network operator makes the corresponding decision within 30 days after the receipt of the documents. If a more detailed inspection of the documents is required, the decision will be made within 60 days after the receipt of the documents.
Obligations of the network operator in case of connecting the generating installations of a power plant to the network 1 The network operator shall Trading Wind System the following remote measurement results concerning the power plant connected to its network to the system operator: 1 in real time the sum of active and reactive loads supplied to power plants with the rated active power from kW to 1 MW.
The data concerning wind turbines shall be presented separately.
My RT allows for:
The requirements are applied also to wind farms with the rated active power of over 5 MW and power plants with the rated active power below 5 MW unless otherwise provided for in this Regulation. Requirements applied to generators and voltage regulators 1 [Repealed — RT I37, — entered into force Upon determining the ceiling voltage other requirements applied to voltage control shall also be taken into account.
Upon designing an excitation system, it must be taken into account that the requirements to ceiling voltage shall be satisfied also during close network faults.
In addition to automatic control, an excitation system shall enable to control the excitation current manually. It must be possible to limit the output signal of the damper and the settings of the limitation shall be adjustable. Different control means may be applied depending on the reactive power output or the power factor.
The use of the control system shall be approved by the transmission network operator. The system operator shall evaluate the drop. Application of additional measures is recommended to avoid the decrease of power output.
The output power may decrease, if stable operation at full power can be restored when the frequency drops below In this case, the generator must switch over to auxiliary load.
Pressure belts of Earth and types of winds - Geography - by TVA
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.

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. Effcient co-generation will receive 5.

According to producer-submitted data and an Elering analysis, subsidized wind energy quantities will grow the most next year - by 73 percent - and quantities from biomass will increase by 15 percent.
Quantities generated in co-generation mode will increase by 7 percent.
Elering is bound by the Electricity Market Act to prepare and release the size of the renewable energy fee by December 1 of each year. The calculation is based on the forecasted quantities generated in the next year, the amount in subsidies needed to support them, projected consumption based on the net consumption in the last 12 months and amounts received in the previous year either in surplus or deficit.
