Abstract: This paper develops bidding strategy for operating multiunit pumped-storage power plant in a day-ahead electricity market. Based on forecasted hourly market clearing price, the objective is to self-schedule and maximize the expected profit of the pumped-storage plant, considering both spinning and nonspinning reserve bids and meeting the technical operating constraints. Evolutionary tristate particle swarm optimization (ETPSO) based approach is proposed to solve the problem, combining basic particle swarm optimization (PSO) with tristate coding technique and genetics-based mutation operation. The discrete characteristic of a pumped-storage plant is modeled using tristate coding technique and mutation operation is used for faster convergence. The proposed model is adaptive for nonlinear 3-D relationship between the power produced, the energy stored, and the head of the associated reservoir. The proposed approach is applied for a practical utility consisting of four units. Simulation results for different operating cycles of the storage plant indicate the attractive properties of ETPSO approach with highly optimal solution and robust convergence behavior.

TL;DR: In this paper, a bidirectional converter connected with battery storage is controlled based on the voltage of the micro grid in order to tackle the aforementioned problem of voltage instability.
Abstract: Providing stable voltage at nominal level according to universally accepted standards is a primary concern of any public electricity network. In a renewable energy fed power electronic based DC microgrid system, renewable sources can have fluctuating power characteristics due to various environmental factors. In such an environment, chances of voltage instability are highly probable due to varying power nature of renewable sources and loads connected. In this paper, a bidirectional converter connected with battery storage is controlled based on the voltage of the micro grid in order to tackle the aforementioned problem. A selector based control algorithm in conjunction with proportional integral controller is used to trigger the bidirectional converter. Proposed control technique is simulated and implemented in a 60V DC microgrid and results are analysed.

TL;DR: A standardized review of these control strategies is discussed as part of this work, and a comparative study among these techniques is made so as to help a designer to choose the apt technique for controlling the microgrid.
Abstract: The DC Microgrid concept has been flourishing in the recent times due to its intrinsic advantages like Renewable Energy Source (RES) compatibility, easier integration with storage utilities through Power Electronic Converters (PECs) and distributed loads. In-depth researches are going on in this field, as the concept of DC Grid can be considered as a master foundation in the realization of Smart Grid (SG) technologies. To achieve this, a number of constraints such as voltage regulation, islanding detection, allowable transient levels, etc. are to be met in accordance with globally accepted standards. The system should have a proper control scheme to keep the things reliable, fault-free and interoperable. In order to meet the constraints as per globally recognized standards, quite a few classes of control algorithms are adopted namely, Centralized, Decentralized and Distributed control. A standardized review of these control strategies is discussed as part of this work. A comparative study among these techniques is made so as to help a designer to choose the apt technique for controlling the microgrid.

TL;DR: This study analyzed various prospects of the country in renewable energy and discusses in-depth about the three Indian states, namely Karnataka, Gujarat, Tamil Nadu, which pioneers the renewable energy production in India.
Abstract: Clean and environment-friendly energy harvesting are of prime interest today as it is one of the key enablers in achieving the Sustainable Development Goals (SDGs) as well as accelerates social progress and enhances living standards. India, the second-most populous nation with a population of 1.353 billion, is one of the largest consumers of fossil fuels in the world which is responsible for global warming. An ever-increasing population is projected until 2050, and consequently, the energy demand in the upcoming decades will be co-accelerated by the rapid industrial growth. The Ministry of New and Renewable Energy (MNRE) with the support of National Institution for Transforming India (NITI) Aayog is working to achieve the Indian Government's target of attaining 175 GW through renewable energy resources. Many Indian states are currently increasing their renewable energy capacity in an objective to meet future energy demand. The review paper discusses in-depth about the three Indian states, namely Karnataka, Gujarat, Tamil Nadu, which pioneers the renewable energy production in India. The global energy scenario was discussed in detail with Indian contrast. Further, the barriers to the development of renewable energy generation and policies of the Indian government are discussed in detail to promote renewable energy generation throughout India as well as globally since the challenges are similar for other nations. This study analyzed various prospects of the country in renewable energy which has been done in a purpose to help the scholars, researchers, and policymakers of the nation, as it gives an insight into the present renewable energy scenario of the country.
