New Technical Regulations? - With the Increasing use of Renewables in Asia, the German and European Grid Code Provides a Suitable Reference Models for Asia Planners, Legislators or Consultants’ Specifying Generators (Room Nile 1)

Power Generation of renewable and decentralized power generation units has been increased strongly over the past few years. This reduces the share of large-scale power plants in power production. Therefore large-scale power plants are less available to provide the grid with necessary system services to ensure power system stability. For this reason it is necessary that renewable and decentralized power generation systems take their share to provide system services to the grid. Grid Codes meanwhile provide regulations to required system services from renewable and decentralized power generation units. In Europe ENTSO-E together with different stakeholders has developed a network code on requirements for grid connection of generators (NC-RFG). A draft of this guideline was approved from the Cross Border Committee in Jun 2015 and will now go for scrutiny into the European Parliament. After this guideline is in force each member state has two years’ time to integrate this European directive into national laws. The NC-RFG defines a frame of requirements for the national guidelines but a lot of requirements are not defined exhausted. For manufacturers of distributed energy equipment this system has a lot of disadvantages. If there is only a frame given from the NC-RFG each country has the possibility (and duty) to define their own boundary’s in the frame. So an unique European design for CHP unit is not possible. The new NC-RFG will have strong influence on already existing national Grid Codes for example because of different methodology in categorize power producers and combine these categories with the different requirements. This paper will examine the requirements from Gird Codes, explain the differences between existing German Grid Code and the NC-RFG and name the future influence on Generator technology and control functions caused by these requirements.
