“…Although the available fast tertiary reserve for positive increment is significantly higher, the minimum value should be considered according to (7). Thus, based on (9), the installed power in WPP that can operate without interruption is around 2901 MW.…”

Abstract:Wind energy integration is a complex target that could refer to different aspects such as: grid capacity; power system; support scheme; environmental; social issues; etc. It is probably the less predictable renewable energy sources (RES) due to its high volatility being difficult to be securely integrated into the power systems. This paper will focus on the wind energy integration from the power system point of view, emphasizing the case of Romania. Before going into the Romanian case, the paper analyzes the potential benefits of the regional approach in terms of power system integration, revealing that it can bring significant advantages by reducing the required power reserves or increasing wind power plants (WPP) generation. Currently, the power system integration is one of the major obstacle to large scale wind energy penetration in the region of Southeast (SE) Europe with high wind energy potential. The results of our research consist in proposing a model for estimating the balancing reserves sharing at regional level, comparing regional to country-by-country approach in terms of the power reserve requirements for balancing the operation of WPP. It definitely reveals that by regional Transmission System Operators (TSO) coordination; less reserves are needed; therefore, the space for RES enlarges. We also propose a model for Romanian power system that is able to calculate the installed power of WPP that could operate without considerable interruptions. Also, the model estimates the additional power reserves required for larger wind energy integration. This perspective can provide interesting insights on what should be foreseen as reasonable behavior of the policy makers and investors.

“…Restriction so far has mostly involved wind generation, for it is the most widespread non-programmable resource worldwide, it is less predictable than PV and it is generally located in remote areas. Wind curtailment is determined by two main causes: transmission constraints and grid stability issues [7][8][9].…”

Improvement of Wind Energy Production through HVDC Systems

et al. 2017

Variable and non-programmable resources, such as solar and wind, have undergone a stunning growth in recent years and are likely to gain even more importance in the future. Their strong presence in the national electricity mix has created issues in many countries regarding the secure operation of the power system. In order to guarantee the stability of the system, several TSOs have resorted to wind energy curtailment, which represents a waste of clean energy and an economic loss. In order to analyze this issue, a model of the Italian power system was developed, a program able to simulate the electricity dispatching mechanism. The model was, then, used to evaluate possible solutions to reduce wind curtailment. In particular, a proposal for the construction of an HVDC line linking Southern and Northern Italy was studied.

“…It was also concluded that efficient wind-power forecasting can help to mitigate the impact of WPPs on the system's operation and costs, but only if used appropriately. A review of studies about WPP integration in the power systems of different countries was given in [11], with a focus on power-system modelling methods and different ways of collecting the data and estimating the regulating and balancing reserve requirements. In [12÷15] the authors discuss different methods for calculating the operating reserve by considering windpower forecasts.…”

“…However, even when considering wind power, such approaches may exclude large changes and tend to underestimate the RR [11]. Therefore, instead of using historical data [12÷19], the actual data from the information system in the dispatch centre can be applied for the daily and hourly forecasts of wind-power generation and load demands [22,23].…”

Original scientific paper This paper presents new approach to the optimal distribution of the regulating reserve (RR) in a set of available regulating generation units. It is developed using evolutionary computation for the transmission-loss minimization and power-flow computation by applying the iterative method with a reactive power correction for voltage control. The approach involves the use of actual operating data directly from the network's dispatch centre as well as daily and hourly plans of wind and load power for determining the RR requirements for the load frequency control (LFC). By testing the proposed approach on a case study, the possibility of implementing it on real power systems is demonstrated. The obtained results of the testing with actual data from the Croatian control area indicate substantial savings in ancillary service costs for the LFC and the considerable impact of different variations from the plan of each individual wind-power plant on the optimal RR distribution.Keywords: evolutionary computation; frequency control; optimization; power system; regulating reserve; wind power generation Utjecaj proizvodnje iz vjetroelektrana na planiranje regulacijskih rezerviIzvorni znanstveni članak Ovaj članak predstavlja novi pristup za određivanje optimalne raspodjele regulacijskih rezervi (RR) između raspoloživih regulacijskih proizvodnih jedinica. Razvijen je korištenjem evolucijskog algoritma za minimiziranje gubitaka prijenosa i proračuna tokova snaga iterativnom metodom sa korekcijom reaktivne snage za regulaciju napona. Ovaj pristup uključuje uporabu stvarnih operativnih podataka izravno iz dispečerskog centra, kao i dnevne i satne planove potrošnje i proizvodnje iz vjetroelektrana za utvrđivanje potrebne snage za regulaciju frekvencije. Testiranjem predloženog pristupa na studiji slučaja, pokazana je mogućnost primjene na realnim elektroenergetskim sustavima. Dobiveni rezultati ispitivanja sa stvarnim podacima Hrvatskog kontrolnog područja pokazuju znatne uštede u troškovima pomoćnih usluga i uočljiv utjecaj različitih odstupanja proizvodnje od plana svake pojedine vjetroelektrane na optimalnu raspodjelu RR.
