  • Measurement of the power battery leasing price based on the Internal Rate of return method
    Dianli Xitong Zidonghua Automation of Electric Power Systems, 2011
    Co-Authors: Bo Sun, Zemin Wang, J Jiang, Tian-shu Bi
    Abstract:

    The Internal Rate of return method is adopted to measure the leasing price for batteries based on two principles, the users' electricity cost is as much as oil cost and the annual yield of the leasing company is as much as a 5-year loan interest Rate. Taking electric buses as an example, under the condition of excluding and that of including the charging infrastructure investment cost, the battery leasing price and the funding gap are measured in three ways, that is, giving all subsidies to the leasing company, giving national subsidies to the leasing company and local subsidies to the users, giving all subsidies to the users. Under the condition of the oil cost remaining unchanged and that of rising by 30%, the curve of the ratio of change in leasing price for batteries and funding gap to the decline in battery prices is given. Finally a constructive scheme for battery leasing is presented based on analysis and comparison of the data. © 2011 State Grid Electric Power Research Institute Press.

  • Chisini means and rational decision making: equivalence of investment criteria
    Mathematics and Financial Economics, 2018
    Co-Authors: Carlo Alberto Magni, Piero Veronese, Rebecca Graziani
    Abstract:

    A plethora of tools are used for investment decisions and performance measurement, including net present value, Internal Rate of return, profitability index, modified Internal Rate of return, average accounting Rate of return. All these and other known metrics are generally considered non-equivalent and some of them are regarded as unreliable or even naïve. Building upon Magni (Eng Econ 55(2):150–180, 2010a , Eng Econ 58(2):73–111, 2013 )’s average Internal Rate of return, we show that the notion of Chisini mean enables these tools to be used as rational decision criteria. Specifically, we focus on 11 metrics and show that, if properly used, they all provide equivalent accept–reject decisions and equivalent project rankings. Therefore, the intuitive notion of mean is the founding basis of investment decision criteria.

  • the Internal Rate of return approach and the airr paradigm a refutation and a corroboration
    The Engineering Economist, 2013
    Co-Authors: Carlo Alberto Magni
    Abstract:

    This paper shows that the Internal-Rate-of-Return (IRR) approach is unreliable, and that the recently introduced Average-Internal-Rate-of-Return (AIRR) model constitutes the basis for an alternative theoretical paradigm of Rate of return. To this end, we divide the paper into two parts: a pars destruens and a pars construens. In the "destructive" part, we present a compendium of eighteen flaws associated with the IRR approach. In the "constructive" part, we construct the alternative approach from four (independent) economic intuitions and put the paradigm to the test by showing that it does not suffer from any of the flaws previouslyinvestigated. We also show how the IRR, as a Rate of return, is absorbed into the new approach.

  • interval and fuzzy average Internal Rate of return for investment appraisal
    Proyecciones Financieras y Valoración, 2012
    Co-Authors: Maria Letizia Guerra, Carlo Alberto Magni, Luciano Stefanini
    Abstract:

    In investment appraisal, uncertainty can be managed through intervals or fuzzy numbers because the arithmetical properties and the extension principle are well established and can be successfully applied in a rigorous way. We apply interval and fuzzy numbers to the Average Internal Rate of Return (AIRR), recently introduced for overcoming the problems of the traditional Internal Rate of Return (IRR). In the setting of interval and fuzzy arithmetic, we establish relations between the interim capitals invested, the profits and the cash flows, which are the ingredients of the AIRR, and shed lights on the different ways uncertainty propagates depending on which variable is known and which one is derived. The relations between fuzzy AIRR and fuzzy Net Present Value are also investigated.

  • Purely Internal Rate of Return and Investment Decisions: A Cash-Flow Perspective
    2010
    Co-Authors: Carlo Alberto Magni
    Abstract:

    The recent notion of Average Internal Rate of Return (AIRR) [Magni 2010, The Engineering Economist, 55(2), 150-180] completely solves the long-standing problem of the Internal Rate of return (IRR). While the AIRR is a return measure, this paper presents a cash-flow measure, namely the ratio of net cash flow (i.e., cash inflows minus cash outflows) to capital invested. It is a purely Internal measure because, unlike the AIRR, it does not depend on the market Rate, and is a return measure as well, for it can be derived from the AIRR by setting the market Rate equal to zero. Therefore, it is a Purely Internal Rate of Return (PIRR). The PIRR is reliable in both accept/reject decisions and project ranking, in association with an appropriate hurdle Rate, economically significant: the comprehensive cost of capital (CCOC), which takes into account not only the interest foregone on the capital actually employed, but also the interest foregone on the capital that is given up by the investor. This perspective enables one to decompose the project NPV into an excess-Rate share and an excess-capital share. The traditional IRR is just a particular case of both AIRR and PIRR, but the latter approach has the advantage that the IRR´s nature (Rate of return versus Rate of cost) does not depend on the market Rate and is unambiguously determined by the capital invested.

  • Transmission System Reliability Evaluation in the Central-1 and Northern Regions of the Lao PDR in Corresponding to Transmission System Development Plan
    2009 Asia-Pacific Power and Energy Engineering Conference, 2009
    Co-Authors: P. Kongmany, S. Premrudeepreechacharn, K. Charoenpatcharakij
    Abstract:

    This paper investigates the 115 kV transmission system development plan of Electricite du Laos (EDL), specifically for the transmission line projects in the Central-1 and Northern regions of the Lao PDR for the years 2010-2020. The steady-state power flow analysis at peak demand conditions is based on N-l contingency criterion. The adjustment in transmission system development plan of EDL is to improve the reliability of such regional networks for the given years based on the economic justification (economic Internal Rate of return, EIRR and benefit cost ratio, B/C Ratio). The economic justification will be accomplished to indicate the Internal Rate of return and benefit cost ratio of each transmission system expansion project. This paper is used DIgSILENT program to calculate the steady-state power flow analysis and Transmission System Reliability Assessments. The results of the studies have shown that, power losses, energy not supplied (ENS), system average interruption frequency index (SAIFI), system average interruption duration index (SAIDI), are also reduced. In addition, the economic Internal Rate of return (EIRR) and benefit cost ratio, (B/C Ratio) of each project can assist planers to make a reasonable discussion or determination to reinforcement and expansion planning.

  • Transmission system development planning for Central-1 and Northern regions of Lao PDR

The power flow analysis at peak demand conditions is based on N-1 contingency criterion. The adjustment in transmission system development plan of EDL is to improve the reliability of such regional networks for the given years based on the economic justification (economic Internal Rate of return, EIRR). The economic justification will be accomplished to indicate the Internal Rate of return of each transmission system expansion project. This paper is used DIgSILENT program to calculate the power system index. The results of the studies have shown that, power losses, energy not supplied (ENS), system average interruption frequency index (SAIFI), system average interruption duration index (SAIDI), are reduced. In addition, the economic Internal Rate of return (EIRR) of each subproject can assist planers to make a reasonable discussion or determination to reinforcement and expansion planning.

  • the Internal Rate of return of photovoltaic grid connected systems a comprehensive sensitivity analysis
    Renewable Energy, 2010
    Co-Authors: D L Talavera, G Nofuentes, J Aguilera
    Abstract:

    At present, photovoltaic grid-connected systems (PVGCS) are experiencing a formidable market growth. This is mainly due to a continuous downward trend in PV cost together with some government support programmes launched by many developed countries. However, government bodies and prospective owners/investors are concerned with how changes in existing economic factors – financial incentives and main economic parameters of the PVGCS – that configure a given scenario may affect the profitability of the investment in these systems. Consequently, not only is a mere estimate of the economic profitability in a specific moment required, but also how this profitability may vary according to changes in the existing scenario. In order to enlighten decision-makers and prospective owners/investors of PVGCS, a sensitivity analysis of the Internal Rate of return (IRR) to some economic factors has been carried out. Three different scenarios have been assumed to represent the three top geographical markets for PV: the Euro area, the USA and Japan. The results obtained in this analysis provide clear evidence that annual loan interest, normalised initial investment subsidy, normalised annual PV electricity yield, PV electricity unitary price and normalised initial investment are ordered from the lowest to the highest impact on the IRR. A short and broad analysis concerning the taxation impact is also provided.

  • tables for the estimation of the Internal Rate of return of photovoltaic grid connected systems
    Renewable & Sustainable Energy Reviews, 2007
    Co-Authors: D L Talavera, G Nofuentes, J Aguilera, M Fuentes
    Abstract:

    A continuous decrease trend in PV costs together with a wide variety of supporting measures have turned photovoltaic grid-connected systems (PVGCS) into a profitable investment when some economic conditions are met. The Internal Rate of return (IRR) is a meaningful parameter for prospective owners of these PV systems. Nevertheless, this parameter has to be estimated by means of non-analytical methods. This paper presents some easy-to-use tables addressed to estimate the IRR avoiding cumbersome calculations, which is an attractive feature for owners, marketers and designers. Firstly, current and near-term costs of PVGCS are reviewed, together with some financial incentives available at present. This introduces the economic scenario, where the tables are to be used. A short introduction to the economic analysis of these systems provides a solid ground to eventually present the tables intended to the estimation of the IRR. Lastly, three examples demonstRate the use of the tables.
