“…In steady-state stability analysis, a main concern associated with the integration of wind and solar power plants is the intermittent/stochastic nature of the power produced, increasing the uncertainty associated with power system states and the attendant complexity of power system (Sajadi, Kolacinski, & Loparo, 2015). This includes active power and reactive power availability and the power flow across the system.…”

“…Following the integration and operation of renewable power plants in the transmission level, the control of distribution feeders can be affected. This can be characterized into a variety of reasons: (a) change of power flow across the system as a result of redispatch of power plants, (b) new points of power injection (resulted by displacement or replacement of power plants), and (c) topological changes in the system (Sajadi et al, 2015). Figure 8 displays the influence of the integration of a 1,000 MW offshore wind power plant in the PJM transmission system on voltage regulation in the FirstEnergy's distribution feeders.…”

This paper tackles the key challenges for dynamics, control, and automation of power systems that are imposed by the integration of renewable power plants. First, the current practice of automation and control in large-scale power systems are reviewed. Then, dynamics and control of electrical transmission systems are discussed and the issues associated with the integration of large-scale wind and solar power plants are exploited. The discussion carries on with a focus on control of electrical distribution systems and the key issues associated with the integration of distributed generation power plants. An emerging concern in power and energy industry is the dynamic interaction between transmission and distribution systems as a result of technological and topological changes in power systems that can put their control at risk. These topics are also covered in this paper. In terms of automation, the key challenges and opportunities for accommodation of higher penetration and share of renewable energy, as part of the vision for grid modernization, are explored in this paper. Throughout the discussion, some results from the recent studies are shown. This article is categorized under: Energy Infrastructure > Systems and Infrastructure K E Y W O R D S automation, control, dynamics, power systems, renewable energy, stability 1 | INTRODUCTION Power systems are compounded of hundreds of thousands of controllable and noncontrollable components that function in a variety of ways (Machowski, Bialek, & Bumby, 1997). Hence, this complex process requires a superb automation to sustain the power delivery. In current power systems, energy management system (EMS) and distribution management system (DMS) represent the highest level of automation at transmission and distribution systems, respectively. These automation systems include the supervisory control and data acquisition systems and a set of real-time and off-line power system applications. The automation and control of traditional power systems with centralized dispatchable power plants and also the stability related issues have been extensively studied and discussed in the literature, including the studies by

“…These are power electronics based high frequency switching devices combined with passive elements to mitigate PQ issues by controlling the network parameters [31]. Among those devices, static synchronous compensator (STATCOM), static VAR compensators (SVC), dynamic voltage restorer (DVR), and unified power flow controller (UPFC) are effective in resolving PQ issues like harmonics, load unbalancing and to retain voltage regulation [32]- [34]. The DVR, when employed with a proper control scheme, is an efficient device for rectifying power fluctuations occur due to intermittent wind energy.…”

Offshore Wind Farm-Grid Integration: A Review on Infrastructure, Challenges, and Grid Solutions

Recently, the penetration of renewable energy sources (RESs) into electrical power systems is witnessing a large attention due to their inexhaustibility, environmental benefits, storage capabilities, lower maintenance and stronger economy, etc. Among these RESs, offshore wind power plants (OWPP) are ones of the most widespread power plants that have emerged with regard to being competitive with other energy technologies. However, the application of power electronic converters (PECs), offshore transmission lines and large substation transformers result in considerable power quality (PQ) issues in grid connected OWPP. Moreover, due to the installation of filters for each OWPP, some other challenges such as voltage and frequency stability arise. In this regard, various customs power devices along with integration control methodologies have been implemented to deal with stated issues. Furthermore, for a smooth and reliable operation of the system, each country established various grid codes. Although various mitigation schemes and related standards for OWPP are documented separately, a comprehensive review covering these aspects has not yet addressed in the literature. The objective of this study is to compare and relate prior as well as latest developments on PQ and stability challenges and their solutions. Low voltage ride through (LVRT) schemes and associated grid codes prevalent for the interconnection of OWPP based power grid have been deliberated. In addition, various PQ issues and mitigation options such as FACTS based filters, DFIG based adaptive and conventional control algorithms, ESS based methods and LVRT requirements have been summarized and compared. Finally, recommendations and future trends for PQ improvement are highlighted at the end.INDEX TERMS Frequency control, Grid codes, harmonics, LVRT, offshore wind energy, power quality, stability, voltage control.

“…A number of studies have investigated the effects of wind power plant integration on power system operation and have recommended various techniques for steady-state analysis, but mainly for land-based wind generation and the integration into distribution and sub-transmission systems. The authors of [2] introduced an error-based index to measure voltage regulation with implications of how different types of offshore wind generators can impact voltage regulation in distribution feeders when integrating a wind power plant at the transmission level. This study suggested that voltage regulation in distribution feeders is a function of location of the point of interconnection (POI).…”

Statistical Steady-State Stability Analysis for Transmission System Planning for Offshore Wind Power Plant Integration

2020

View full text Add to dashboard Cite

This paper presents a statistical steady-state stability analysis for transmission system planning studies in order to identify operational issues inherent in the integration of offshore wind power plants. It includes normal and contingency operation. This study considers the integration of a 1000-MW offshore wind power plant into the FirstEnergy/PJM service territory in the U.S. Great Lakes region as a case study and uses a realistic computer model of the U.S. EasternInterconnection, a 63,000-bus test system. The results show the utility of this statistical analysis tool and its effectiveness in identification of the operational impacts as a result of the integration of offshore wind power plant.
