Abstract: In the contemporary world, the use of energy, especially electrical energy, is increasing rapidly. Without this power, modern civilized life cannot think for a moment. Thereby a huge amount of electrical energy is needed. We have to generate a considerable amount of electricity to meet the growing demand maintaining necessary conditions and constraints. A rapid ergent strategy called Economic Load Dispatch (ELD) has been introduced to distribute generated energy economically during times of crisis. The problem of economic load dispatch is solved with the help of Optimal Power Flow (OPF) formation. The OPF is a primary tool related to the optimum generation schedule available in an interconnected power system to reduce production costs subject to the limitations and constraints of the relevant system. The static economic dispatch optimizes over single dispatch intervals, which is called “ED static”. Due to high load variability and uncertainty, the ED-static is not working properly. Thereby a deterministic look-ahead dispatch is established, which takes care of the increasing renewable penetration. To take decisions against uncertainty, stochastic load dispatch is required. In this research paper, an economic study of the modified IEEE 5 bus power system will be presented. Moreover, some intelligent changes to this system will include the goal of reducing costs, including maximum power supply. The optimal power flow of the modified IEEE 5 bus system considering plausible scenario will represent based on stochastic load dispatch optimization model. The extension version of Economic load dispatch where load flow equations are applied, and as a system of supply-demand balance constraints is called optimal power flow. To solve the optimal power flow Lagrangian method is used. Karusk-Khun-Tucker (KKT) conditions are applied to solving the Lagrangian method. The results show that during uncertainty and stochastic loads, the storage system with renewable power and generator is suitable for cost reduction with maximum supply. The results further show that for any type of loads, such as fixed load and stochastic load in IEEE 5Bus system, if both renewable energies, such as wind power, solar power, the storage devices are used in the generation system, which ensures maximum power supply with the cost is reduced.

The Role of Demand Response Aggregators and the Effect of GenCos Strategic Bidding on the Flexibility of Demand
Publisher: MDPI AG

DOI: 10.3390/EN11123296
Abstract: This paper presents an interactive trading decision between an electricity market operator, generation companies (GenCos), and the aggregators having demand response (DR) capable loads. Decisions are made hierarchically. At the upper-level, an electricity market operator (EMO) aims to minimise generation supply cost considering a DR transaction cost, which is essentially the cost of load curtailment. A DR exchange operator aims to minimise this transaction cost upon receiving the DR offer from the multiple aggregators at the lower level. The solution at this level determines the optimal DR amount and the load curtailment price. The DR considers the end-user’s willingness to reduce demand. Lagrangian duality theory is used to solve the bi-level optimisation. The usefulness of the proposed market model is demonstrated on interconnection of the Pennsylvania-New Jersey-Maryland (PJM) 5-Bus benchmark power system model under several plausible cases. It is found that the peak electricity price and grid-wise operation expenses under this DR trading scheme are reduced.
Key items for reports of primary care research: an international Delphi study

Abstract: Reporting guidelines can improve dissemination and application of findings and help avoid research waste. Recent studies reveal opportunities to improve primary care (PC) reporting. Despite increasing numbers of guidelines, none exists for PC research. This study aims to prioritise candidate reporting items to inform a reporting guideline for PC research. Delphi study conducted by the Consensus Reporting Items for Studies in Primary Care (CRISP) Working Group. International online survey. Interdisciplinary PC researchers and research users. We drew potential reporting items from literature review and a series of international, interdisciplinary surveys. Using an anonymous, online survey, we asked participants to vote on and whether each candidate item should be included, required or recommended in a PC research reporting guideline. Items advanced to the next Delphi round if they received % votes to include. Analysis used descriptive statistics plus synthesis of free-text responses. 98/116 respondents completed round 1 (84% response rate) and 89/98 completed round 2 (91%). Respondents included a variety of healthcare professions, research roles, levels of experience and all five world regions. Round 1 presented 29 potential items, and 25 moved into round 2 after rewording and combining items and adding 2 new items. A majority of round 2 respondents voted to include 23 items (90%–100% for 11 items, 80%–89% for 3 items, 70%–79% for 3 items, 60%–69% for 3 items and 50%–59% for 3 items). Our Delphi study identified items to guide the reporting of PC research that has broad endorsement from the community of producers and users of PC research. We will now use these results to inform the final development of the CRISP guidance for reporting PC research.

Abstract: A solar tracker is a system for orienting solar photovoltaic modules and solar thermal collectors toward the sun. This paper presents a microcontroller based energy efficient hybrid automatic solar-tracking system with a view to assess the improvement in solar conversion efficiency. The two-axis solar-tracking system is constructed with both hardware and software implementations. The proposed tracking system uses a new solar position sensor with adaptive features. A comparative analysis was performed using four systems, i.e., hybrid tracking, dual-axis, single-axis, and stationary module. The results showed that the use of the dual-axis tracking system produced 18% gain of power output, compared with a single-axis tracking system. The gain of output power with the hybrid tracking system was much higher (54%) when compared with a stationary system inclined at 23.5 deg to the horizontal. Considering the state of the art of the technology, successful strategy, robust control philosophy, and the potential added benefit of this research work can be employed on a large scale in sustainable manner.
Optimal Power Delivery from Hybrid Micro-grid to Provide Frequency Regulation

DOI: 10.2174/2352096512666191111120050
Abstract: This paper presents an optimal power delivery system for a hybrid microgrid consisting of a solar PV, wind farm, battery storage and diesel generator. The fuzzy logicbased control approach is used to match the generation and consumers’ demand. The load demand is assumed to vary hourly in a day and season to season in a year. The frequency of AC (alternating current) bus may deviate from standard frequency due to supplydemand imbalance and thus make the system unstable. To overcome the situation, the controller actuates a control signal to maintain system frequency. Frequency deviation is an indication of the load change and battery voltage (state of charge) is taken as input. In case of excessive generation, the extra power will be absorbed in the dump load for an isolated system. Whereas, for a grid-connected system, the surplus generation is fed into the grid. This cost-effective control method ensures the balance between generation and load demand at all times.
