Sažetak
The paper will present the process of the planned grid connection scheme optimization for wind power plants. At start the overview of the current status and trends will be observed alongside a short description of the Croatian power system specifics. The special highlight will be given to the wind energy integration. Following, the potential problems regarding the reduced inertia, more complicated protection requirements and regulation issues will be shortly described. The paper will provide technical description and graphical representation of potential grid connection solutions. Then, description of the calculation of different scenarios of load flows to select the optimal grid connection solution will be explained. The prerequisite for the power flow calculations is always the development of the thorough grid model which will also be described briefly. Furthermore, the relevant and influencing new network changes and users must be chosen to measure their influence through inclusion into the model and future scenarios selection importance will be discussed. Based on the determined grid connection point and terrain characteristics optimization of the wind power plant layout needs to be done to reduce the losses combining the statistical analysis and power flow analysis. This results in the transformer stations positions selection and desired voltage level selection. Finally, estimation and analysis of grid connection costs and potential production levels shapes the final recommendations. Throughout the paper described general methodology will be applied to a hypothetical case study and results and conclusion will be shown.
