Saturation phase of building-integrated photovoltaics (PV) is described, for which multi-agent simulations coupled with electric power flow analysis are carried out. The detailed power flow analysis determines the probability of reverse current occurrence due to the additional PV installation in a 6.75 kV-class power network consisting of 2500 grid-connected individual customers. The agent-based simulation including the customer agent and government agent describes the timedependent behavior of PV saturation-phase in an artificial society as determined through the power flow analysis. Growth in share of PV is assisted by a battery installation as a reservoir for the reverse power current. On the other hand, the excessive promotion for PV installation by the government results in the increase in the cost of reverse current care. I. INTRODUCTIONIntegration of renewable energy sources in power networks is an emerging subject of electrical engineering as related to dispersed generation technology and environmental engineering. To design a survivable society in 21st century, technology and human nature have to be in harmony. As an instrumentality of energy sciences, a working project of "complexity-based emergent approach to survivable energy¢environment design (cSEED)" has been in progress [1] [6]. Figure 1 shows a conceptual illustration of a virtual society consists of renewable energy sources and an electrical power network. Solar energy, wind energy, and biomass energy are integrated in a power network with power plant, transmission facility, and energy storage system, so that they can interact with human society (customer).The focus of this work is to predict the saturation-phase of building-integrated photovoltaics (PV) in an artificial virtual society by using multi-agent simulations coupled with electric power flow analysis. Complex system is a new approach to science that studies how relationships between parts give rise to the collective behaviors of a system and how the system interacts and forms relationships with its environment [7], [8]. The multi-agent system is one of the computational models for simulating the actions and interactions of autonomous individuals with a view to assessing their effects on the system as a whole [9], [10], [11]. The present agent-based models includes Two kinds of agent, that is, customer agents and a government agent. Ability of decision-making and learning rules for customer agents.

“…The contribution of the voltage supplied by the photovoltaic system is the difference between the voltage drop ∆V in line with and without GPV, the relationship of the voltage drop between the upstream network and the connection point of a PV system is determined as follows [8]. Each piece of power line is cut up into segments or dipoles where clients are distributed.…”

Abstract:The photovoltaic applications are no longer limited to their use in remote sites. The current trend, particularly in industrialized countries is connected to the power grid individual installations, especially collective facilities and projects in the courtyard of this century will surely change our energy consumption habits. As part of this work we considered the use of mini photovoltaic plants connected to the low voltage grid as a means of compensation, generating electricity at the point of deficit. For this we analyzed the behavior of a MV / LV, which has voltage drops in two starts and tried to connect at the end of each starting of a photovoltaic mini plant in order to bring the network technical parameters (power voltage) in permissible limits.

“…The electrical distribution utility has to satisfy some constraints about the power quality provided to its customers (Standard EN 50160 [2]. One of these constraints is on the voltage, therefore if the voltage reaches a too high value, the PV systems could be stopped just when the power generated could be maximum (output restriction [3] [4] of the Power Penetration). In this paper the attention will be focused on the possible problem of voltage rise in two different situation.…”

This paper presents the problem of the power penetration of photovoltaic (PV) systems in urban networks. After a qualitative problem description, two different environments for the PV systems have been analyzed: rural and urban networks. Concerning the rural network a single line has been simulated in order to evaluate the relation between the number of PV system installed along the line and the maximum PV power installable. In the second part of the paper the possible problems due to the power penetration have been examined concerning a clustered PV system that will be installed in the city of Torino (Italy) in ambit of an EU project.
