“…For building owners considering a renewable energy installation, investment analysis requires predicting future electricity prices. A common method for pricing is to assume the most recent retail electricity price and apply it to all hours of the year [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. This is usually a reasonable assumption given that in many places where grid connected PV is installed, owners are given a fixed feed-in tariff (FiT), power purchase agreement (PPA) or have net metering based on a static retail price [22].…”

a b s t r a c tThe use of hourly prices in distributed photovoltaic (PV) techno-economic analysis is rare, but may become necessary as time-of-day retail pricing becomes more common. A methodology is presented for selecting an hourly price curve suitable for long-term analysis, called the typical price year (TPY), which is based on the methodology for TMY weather data. Using a techno-economic analysis with annual revenues and net present value as indicators, a TPY curve for the Swedish market is validated and then compared to 18 price simplification methods to determine the error introduced by the use of non-hourly prices. Results show that the TPY method produces a curve which accurately represents long term pricing trends, but using a static annual mean introduces minor revenue errors of 1.3%. This suggests the TPY may not be necessary in the Swedish market, but further analysis of the method is suggested for other markets.

“…The cost per Wpeak for this system is $10.20. It should be noted that the price per Wpeak in Brazil is equal to the worst case among the European countries mentioned by [17]. The results found by [18] show that the photovoltaic system becomes feasible if its price is under $6.00 per Wpeak in Japan.…”

Simulation of Distributed Generation with Photovoltaic Microgrids—Case Study in Brazil

et al. 2015

Elevated prices and lack of proper legislation and government incentives have been the main barriers in the development of the photovoltaic market in Brazil. In an attempt to overcome those barriers, a microgrid model was proposed and simulated. In the proposed microgrids, residential consumers are connected to each other to maximize the investment return by trading the surplus of generated energy among them. Different topologies and scenarios were studied from electrical energy and economic standpoints. Stochastic data of solar radiation were simulated for the city of Viçosa, Minas Gerais, Brazil, for the period of one year, considering the statistical behavior of a series over 20 years. The system output power and energy balance were calculated considering a model for photovoltaic generators and the radiation simulated data. By determining the generated energy and electrical needs of the microgrid members, the cash flow and economic feasibility were calculated. Sensitivity analyses were performed by varying economic parameters to determine situations where investment becomes feasible. This paper OPEN ACCESSEnergies 2015, 8 4004shows that microgrid contributes to improve the economics and the initial investments. The number of participants in a microgrid, the electricity and the equipment costs are important parameters to speed up the economic and technical feasibility process.

“…These parameters are calculated by initial capital investment, operation and maintenance costs, and battery replacement cost [164][165][166][167]. The cost of generation of PV power is calculated by the concept of levelized cost of electricity (LCOE) and recently it was found to be for the state of Kuwait as 0.28$ [166] and for the Southern Spain as 0.13$ [167].…”
