Title: Greening the Grid (GTG) Annual Report 2018 Application pdf
Synopsis: The GTG program aims to support the Government of India’s (GOI) efforts to manage large-scale integration of RE into the grid. The GTG- Renewable Integration and Sustainable Energy (RISE) Initiative includes design, implementation and scaling of prioritized innovation pilots that support RE integration into the grid and will open up market opportunities for innovative technologies, solutions and services. The GTG-RISE Initiative is implemented by Deloitte Consulting LLP and will run through December 7, 2020. As part of the Initiative, successful deployment and scale-up of these pilot solutions will offer new market opportunities for innovative technologies, solutions and services. These pilots focus on modernizing India’s power system from generation to transmission by making the coal power fleet more flexible; demonstrating the batteries’ value for storage; assessing the technical and economic feasibility of advanced equipment/inverters for grid reliability; and adding automatic controls to generators. The initiative is also working with Indian institutions — national grid operator and electricity regulator — to expand the use, and improve the design of electricity markets by creating an effective intraday power market. The project has achieved several milestones since the inception in year 2017-18, which are detailed in this annual report.

Title: Reactive Synopsis: Power Control Strategies for Solar Inverters to Increase the Penetration Level of RE in Power Grid Application pdf
Synopsis: Integration of Distributed Generation (DG) in active grid depends on the grid parameters viz. strength of the network, voltage etc. Network voltage is one of the limitations for penetration of Renewable Energy (RE) based DG into the active power grid. Solar Photovoltaic power generation is a key source of Renewable Energy Sources (RES), which is integrated through the highly efficient and multi-functional inverters. Capability of Solar Inverters (SI) can be utilized to provide the voltage support during critical system need on a 24/7 basis. During night, entire inverter capacity can be used for reactive power support. During the critical voltage condition in the daytime, SI capacity left after the PV power generation can be utilized to improve the voltage stability of the system without any RE curtailment. This paper presents potential reactive power control schemes for SI, considering enhanced utilization of the inverter reactive power capability to enhance the voltage regulation at the Point of Common Coupling (PCC) under the physical limitation of the inverter. The Solar Inverter Control (SIC) schemes are incorporated in the optimal power flow (OPF), and formulated as an optimization problem, where, the inverter control schemes are applied to maximize the total distributed generation (DG) penetration and enhance the distribution/transmission network utilization in a typical power grid. Various case studies are presented and compared to evaluate the performance. The results show that the proposed reactive power control scheme can significantly increase the wind penetration levels up to 81% depending of the network constrains and integrated RES.

Title: Development of Mechanisms to Incentivize Inter-State Exchange of Renewable Energy Application pdf
Synopsis: Given the geographical variance of RE resources (surplus and deficit RE states) across the country, inter-state RE exchange shall play a critical role in creating more demand and resulting in higher RE capacity additions. To facilitate higher RE exchange across these RE surplus and deficit states, it requires supportive policy and regulatory framework for bringing inter-state RE exchange into the mainstream, which currently is at very low levels. A detailed quantitative and qualitative analysis of prevailing regulatory framework has been performed to understand the missing inter-linkages among the regulations. Also, issues related to transmission infrastructure, and its existing pricing mechanism for evacuation of renewable energy have been reviewed. Currently, power market, commercial and operational processes are developed for high share of coal generation, so as share of RE increases it will be required to develop commercial and operational procedures to facilitate high RE grid integration. Based on this analysis and consultation with a wide array of stakeholders, measures which facilitate inter-state RE exchange have been recommended.

Title: Synopsis: Implementation of Automatic Generation Control at Hydro Power Plants in Southern India Application pdf
Synopsis: Power system reliability under increased RE penetration is of significant concern to system operators. As of now in India, the regulations on tertiary reserve market exist, and are followed by Regional Load Dispatch Centres (RLDCs). Considering the future growth of RE to meet the Government of India (GoI) targets, regulation reserves have been identified as necessary to compensate variations due to the load and RE in the seconds timeframe. Under the pilot, the AGC facilities are planned to implement at two hydro power plants: Sharavathi hydro power plant (10 x 103.5 MW) and Varahi Hydro power plant (4 x 115 MW. The existing AGC module in Energy Management System (EMS) at State Load Dispatch Center (SLDC) is planned to configure to generate the AGC signals for participated hydro units. The paper will analyse the role of ancillary services with focus on secondary control using Automatic Generation Control (AGC).

Title: Study of different use cases of the grid connected Battery Energy Storage System in India Application pdf
Synopsis: Increasing penetration of uncertain and intermittent renewable energy sources (solar, wind) can cause various problems in grid such as dynamic frequency, voltage fluctuations, and demand-supply imbalance. In countries such as India, where has an ambitious target of adding 175GW RE generation to the grid by 2022, may bring more challenges to the grid operators for sustainable and reliable grid operations. However, a fast responding storage device such as Battery Energy Storage System (BESS) could be used to mitigate these problems in real time operation of power system by providing various grid applications including Frequency Regulation, Energy time shift and RE firming etc. But, the regulations for providing ancillary services have not yet been matured across the globe especially in large power grid network countries like India. This paper discuss about various ancillary services provided by the BESS with different battery technologies. Real time implementation of Li-ion, Advanced Lead Acid and Flow battery systems of 1.25MW capacity by POWERGRID has been considered for this study. The study would also provide insights on regulatory and commercial framework to be adopted by Regulators in allowing large RE integration in Indian grid scenarios.

Title: India’s Power System Transition – Insights on Gate Closure Application pdf
Synopsis: Greening the Grid (GTG), a partnership between the U.S. Agency for International Development (USAID) and the Government of India Ministry of Power, released a new analysis on gate closure in the Indian context—a critical feature of electricity market design under consideration by the Central Electricity Regulatory Commission (CERC) to facilitate large-scale renewable integration in India. In defining gate closure, the time at which market participants must submit their final bids and offers for electricity and schedules become firm, CERC will be balancing multiple considerations—jurisdictional control, market efficiency and design, thermal and system operational requirements, communication and infrastructure standards, and RE forecasting accuracy, among others. This report analyzes global experiences with gate closure, and then reviews the unique benefits, challenges, and other considerations that will impact the implementation of gate closure in the Indian electricity market. The analysis can inform decision-making in both the Indian power system, and more broadly across South Asia as electricity markets become more integrated. The report was co-authored by the U.S. National Renewable Energy Laboratory (NREL) and Power System Operation Corporation Limited (POSOCO).
